Bilingual Kids and Speech Delays: What Parents Need to Know
By Lindsey Wood, MOT, OTR/L
You're at a family gathering, and someone leans over with a comment that lands a little too hard: "Maybe he's not talking because you speak two languages at home. It's confusing him." You laugh it off, but later that night, you're lying awake wondering if they were right. Should you drop one language? Are you the reason your child isn't saying as many words as his cousins?
If this is you, take a breath. You haven't done anything wrong — and the advice to "just pick one language" is one of the most common myths we hear at Eat. Play. Love. OT.
Raising a bilingual child in San Diego is a gift, not a delay. But because bilingual development looks a little different, it can be genuinely hard to tell what's typical and what might need a closer look. Let's untangle it together.
Two languages don't cause speech delays
Let's clear this up first, because it's the worry underneath everything else: growing up with two languages does not cause a speech or language delay. Decades of research back this up. Bilingual children are just as capable of hitting their milestones on time as monolingual kids.
Their brains are more than ready for the job. In fact, learning two languages early can strengthen skills like attention, problem-solving, and switching between tasks. What can look like a delay is often just the normal, messy, beautiful process of two languages developing side by side.
So if a well-meaning relative — or even a professional who isn't trained in bilingual development — tells you to give up your home language, please know that the opposite is usually true. Your home language is where your child's deepest connection to family, culture, and identity lives. It's worth protecting.
What's actually normal for bilingual kids
Bilingual children often do a few things that can look concerning if you don't know they're expected. Knowing them ahead of time can save you a lot of 2 a.m. worry.
Mixing languages in one sentence. Your child might say something like "Quiero more leche." This is called code-mixing, and it's a sign of a flexible, developing brain — not confusion. Adult bilingual speakers do it too.
A quiet period. When a child is first immersed in a new language (say, starting preschool in English), they may go quiet in that language for weeks or even months while they soak it in. They're listening and learning, even when they're not talking yet.
Uneven vocabulary. Your child might know food and family words in Spanish and school and toy words in English. That's normal. The trick is that we have to count words across both languages, not just one.
That last point matters more than almost anything else. If someone only counts your child's English words, they might see a "delay" that vanishes the moment you add in the Spanish, Tagalog, Vietnamese, or Arabic words they use every day at home.
When to look a little closer
Here's the part parents actually want: how do you tell the difference between normal bilingual development and a true delay? The answer is that a real speech or language delay shows up in both languages, not just one.
It might be time to check in with a speech-language pathologist if, across both of your child's languages, you notice:
By around 12 months, they aren't babbling, pointing, or using gestures like waving. By 18 months, they have very few words in either language combined. By age 2, they aren't putting two words together (in any language mix). They rarely make eye contact or respond to their name. They seem frustrated a lot because they can't get their message across. You've noticed they've lost words or skills they used to have.
You're not being an overprotective parent for wondering about this. You're being an attentive one. And you don't have to have it all figured out before you ask for help — that's literally our job.
If any of this is ringing true, a pediatric speech evaluation can give you real answers instead of more guessing. A good evaluation with a therapist who understands bilingual development will assess your child across all their languages, not just English.
How we support bilingual families
When you bring your child to us, we won't ask you to abandon your home language. We'll do the opposite — we'll help you lean into it.
We look at your child's whole language system, celebrate the words they have in every language, and coach you on simple ways to build language during the everyday moments you're already having: bath time, snack time, the car ride to Grandma's. You know your child and your languages better than anyone, and that makes you our most important teammate.
Because we see kids in their homes and via telehealth across San Diego County, therapy fits into your real life and your real family — the languages, the food, the routines, all of it.
You're doing better than you think
Choosing to raise your child with more than one language is one of the most loving, forward-thinking things you can do. It connects them to who they are and widens the world in front of them.
And if there's also a delay in the mix? That doesn't erase any of that. It just means your child might need a little extra support to unlock everything those two languages have waiting for them.
If you've been carrying that quiet worry, let's talk it through — no pressure, no judgment. Book a free consultation and we'll help you figure out whether your child is right on track or could use a hand. Either way, you'll walk away with clarity instead of guilt.
