In Park Ridge, 23% of residents age five and older speak a language other than English at home. If you are one of those households, you may have watched your toddler use fewer words than the children at the playground. Bilingual speech delay in toddlers is a common concern, and it’s one reason Park Ridge families reach out for pediatric therapy in Park Ridge.

Two languages don’t cause a delay. A toddler learning both typically starts talking on a similar timeline to a child learning one, but their attention is split. Learn how to count your child’s words across both languages and which signs deserve a closer look. When the signs point that way, speech therapy in Park Ridge is the next step.

Does Being Bilingual Cause a Speech Delay?

Speech delay in Park Ridge bilingual toddlers doesn’t come from learning two languages. Nationally, about one in 14 children ages three to 17 has a disorder of voice, speech, or language, according to the NIDCD. Bilingual children reach the same early milestones as children learning one language. By about age two, most toddlers use two- or three-word phrases and fifty or more words, counted across both languages.

Bilingualism can change how the brain divides words, not how many it can hold. Your toddler may say 15 words in Polish and 15 in English, for a combined 30 words: the same total a monolingual child might reach in one language. One toddler just spreads the words across two languages instead of one.

How Two Languages Build the Same Skills

Your child hears a set number of language hours each week, divided across the two languages at home. That split makes each language look thinner on its own. The underlying system develops on schedule anyway because a toddler builds one set of concepts and attaches two labels. First words still arrive around 12 months, and two-word pairs still show up around 24 months.

How Mixing Both Languages Shows Healthy Growth

When your toddler says “more mleko” at the table, they’re not confusing the two languages. Your child reaches for whichever word comes first, which takes two active vocabularies.

Bilingualism in your toddler can mean a few things:

  • Borrows the faster word: Your child grabs whichever label comes to mind first, in either language.
  • Switches by listener: Your child uses more Polish with grandma and more English at daycare.
  • Keeps both grammars intact: Your child follows the word order that belongs to each language.

None of those habits point to delayed speech in a bilingual Park Ridge household. Each one shows your toddler uses both vocabularies. The words your toddler already says in Polish and in English aren’t competing. They are one vocabulary wearing two labels. The combined number is all that matters, and it sits higher than either single-language count on its own.

How Many Words Should a Bilingual Toddler Say?

Add the words from both languages together. That total is the number to judge. Multilingual children in Park Ridge reach the same milestones as everyone else, with first words by about age one and two-word phrases by about age two. A toddler learning two languages at once who says 20 words in Spanish and 20 in English knows 40 words, safely on track. Counting only English would halve that total and invent a bilingual speech delay your toddler doesn’t have.

Adding Up Your Child’s Total Vocabulary

Write two lists, one per language, and put every word your child uses on the right one. Count a word once even if your child says it in both languages, since that is one concept with two labels. The sum is your child’s combined word count. It’s the figure a speech-language pathologist will ask about. Come back to your two lists in about four weeks and count again. The direction your toddler’s vocabulary is taking tells you more than any single snapshot.

Tracking Milestones in Both Languages

These markers count across both languages together. Read each as a combined total, not a score in one language.

  • Babbles in play: Your child strings sounds together by 12 months, in either language.
  • Says first words: Your child produces a handful of real words by 12 months.
  • Pairs two words: Your child joins words regularly to communicate by 24 months.

A quiet stretch after a move or a new daycare is typical. Check the milestones for toddlers, and the normal range runs wider than parents expect. If that stretch runs past a few months, it’s worth a closer look at a possible bilingual language delay. You now have a number instead of a feeling, and it belongs on the fridge beside your two lists.

Which Signs Deserve a Closer Look in Both Languages?

When your toddler says little in Polish but plenty in English, that’s a language balance. A speech delay in your two-language Park Ridge home looks different, with a small vocabulary and trouble following what is said on both sides.

Toddlers at 30 months typically reach about 50 words, which is the number a bilingual toddler reaches across both lists combined. Every sign below is tied to a specific age for that reason. You are measuring your child against a date, and that distinction matters most when two languages are splitting the week.

  • Babbles very little: Your child makes few sound strings by 12 months, in either language.
  • Says too few words: Your child’s combined list sits well below the age mark, not just behind in one language.
  • Skips two-word pairs: Your child rarely joins two words together by 30 months, six months past when this skill typically shows up.
  • Misses one-step directions: Your child doesn’t follow a simple request in either language.
  • Drops words once used: Your child has stopped saying words they said a few months ago.

Heavy frustration also counts, though it’s harder to pin to an age. Watch for when your toddler gives up mid-sentence or leads you to the fridge instead of asking for milk. That effort, and where it stops, tells you as much as any word count.

How Can You Support Both Languages at Home?

Both languages help your toddler, and dropping one doesn’t speed up talking. A toddler needs plenty of language coming in, so talk more in whichever language comes naturally to you. Parents who switch to their non-dominant language tend to speak less and use shorter sentences, so talk with your child in whichever language you speak most comfortably.

Practice with you is what builds their vocabulary. Park Ridge parents worried about a bilingual speech delay sometimes move to English only, but your child gains more when you stay in the language you speak best.

Your home language isn’t an obstacle to English. It’s the language your child’s grandparents use. Understanding runs ahead of speaking, so a quiet toddler may be taking in far more than they give back. Sorting understanding from speaking matters because a quiet child who understands well sits in a different category.

What shapes your child’s word count? How much language reaches them, in any language. The songs in your bedtime routine are doing more than you can hear. Keep them in the language they belong to. If the signs still hold in a few months, an evaluation turns your two lists into a straight answer, and Illinois law requires your insurance to help cover it.

When Should You Book a Speech-Language Evaluation in Park Ridge?

If the signs from the list above hold in both languages, it’s time for a speech-language evaluation. Confirming a speech delay in your bilingual toddler takes only one visit. No referral or diagnosis is needed. Families in Park Ridge can call CST Academy or start with the online form, and our team follows up within one business day. The evaluation itself is done by a certified speech therapist who understands bilingual development.

A certified speech therapist who understands bilingual development leads each session, with parent coaching so that the strategies carry home. Ask the Park Ridge team about therapy in your home language, since availability varies by clinician.

The visit is play-based. Your child explores toys while the speech therapist watches how they ask and answer.

  • Observes play first: Your child leads the play while the therapist takes notes.
  • Checks understanding next: Your child gets simple requests so that the therapist sees which ones they follow.
  • Reviews your lists last: Your two lists give the therapist a combined count across both languages.

You leave with an in-person debrief, and the written report follows within a week. A speech evaluation answers a question about talking. Speech therapy runs from 18 months to 18 years.

Frequently Asked Questions on Bilingual Speech Delay in Toddlers

These are the questions Park Ridge families bring up when two languages are in the house.

How Do I Know If My Bilingual Toddler Has a Speech Delay?

Bilingual speech delay in Park Ridge can show up in both languages at once. Write two lists, one per language, and count every word your child uses on either list. If the combined total is thin for your child’s age, and your child has trouble following simple requests in both languages, book an evaluation.

Should I Drop One Language to Help My Toddler Talk?

Dropping a language doesn’t speed up talking. It reduces the total amount of language your child hears, since you would be speaking less in the language you know best. Keeping both languages keeps your child connected to grandparents and hearing plenty of language every day. Put your energy into talking more in whichever language comes naturally to you.

My Toddler Mixes Two Languages in One Sentence. Is That a Problem?

That’s not a problem. It’s a sign of two active vocabularies working at once. Your child reaches for whichever word comes first, in either language. They will switch by listener, too, using more of one language with grandma and more of the other at daycare. That control over who gets which language is a skill, and it develops without any coaching from you.

Is My Child Just a Late Talker, or Is It Something More?

A late talker understands what you say and simply starts talking later than other children their age. The difference is comprehension. If your child follows a simple request in either language and brings you what you asked for, understanding is intact, and late talkers often catch up. When understanding lags alongside talking in both languages, the delay is more likely to need support, and an evaluation settles the question.

Do I Need a Referral for a Speech Evaluation in Park Ridge?

You don’t need a referral or a diagnosis to book a speech-language evaluation in Park Ridge. Call or fill out a form and describe what you’ve noticed. A member of the team follows up within one business day. You pick an appointment time that fits your week. The evaluation itself is the first clinical step, so nothing has to happen before it.

Will Speech Therapy Be in English or in Our Home language?

Your child’s therapist delivers sessions in English and coaches you in your home language, so the strategies carry back to your house. Your child’s speech therapist understands bilingual development and accounts for both languages when reading your child’s progress. Ask your Park Ridge team about language support, since availability varies by clinician. Practicing the same words at home in Polish, Spanish, or Korean still counts.

Will Insurance Cover My Child’s Speech Evaluation?

Illinois law requires insurance companies to cover medically necessary speech services for children. Speech delay across bilingual Park Ridge families falls under the same rules as any other speech concern. Your out-of-pocket cost depends on your plan, and the billing team walks you through your coverage before your child’s first session.

Could My Bilingual Toddler’s Speech Delay Be a Sign of Autism?

A speech delay on its own isn’t a diagnosis, and plenty of children with a delay are not autistic. If a broader concern comes up, such as limited response to their name or difficulty following simple directions, a diagnostic evaluation is the right next step. CST Academy provides diagnostic evaluations at our Chicago clinic, and from there the Park Ridge team takes the next step. A speech-language evaluation and an autism diagnostic evaluation are two separate visits.

Start with a Clear Answer for Your Toddler

Two languages give your child something that shows up years later, in a conversation with a grandparent and in a classroom that counts both. The share of Park Ridge households speaking more than one language isn’t a risk factor, and a second language never causes a speech delay on its own. What changes the outcome is knowing what to count and when to ask, and you now have both.

Talk with CST Academy about a speech-language evaluation for your toddler. Call (773) 620-7800 or contact the Park Ridge team through the contact form. Describe what you’ve noticed at home, along with the languages your family uses. You’ll get a clear sense of whether your child needs support, and a first appointment that starts with your two word lists instead of a blank file.
