Is My Bilingual Toddler on Track? An SLP's Honest Answer
By Lindsey Carleton, MA, CCC-SLP
If you’ve ever been awake at night wondering is my child behind?, you are in very good company. It’s the most common worry I hear from bilingual parents — and it usually arrives wrapped in a second one: am I doing this wrong?
You’ve probably already read the reassuring basics (no, two languages don’t cause a delay; yes, mixing them is normal). So instead of repeating that, I want to give you something more useful: a better way to actually tell whether your bilingual toddler is on track — and it’s probably not what you’re measuring.
You’re probably measuring the wrong thing
Most parents track a single number: how many Spanish words their toddler says out loud. It’s the noisiest, least reliable signal there is — spoken words are the last thing to show up, long after the real work is happening underneath. Three quieter signals tell you far more:
- Understanding runs ahead of talking. If your child follows little instructions, points to the right picture, or reacts when you say a word — the language is in there, even when it isn’t coming back out yet. Comprehension is the true leading indicator.
- The drive to communicate. Pointing, gesturing, jabbering, tugging you toward what they want — a child working to be understood is a child on track, regardless of the word count.
- Something new every few weeks. Not every day. Bilingual growth comes in bursts and plateaus, so the real question isn’t “how many words today?” but “is the trend still moving over a month?”
Ask a better question than “is my child behind?”
Here’s the reframe that actually helps. “Is my child behind?” is a question about your child — which you can’t control, and which feeds the 2am spiral. Swap it for three questions about your setup, which you can:
- Is the exposure consistent? Ten minutes of Spanish every day beats an hour every Sunday. Little and often is how language takes root.
- Is it interactive — with a person, not a screen? Language grows in back-and-forth. One minute of real conversation outweighs an hour of Spanish cartoons.
- Does my child have a reason to use it? A person they love who speaks it; a need it meets. Kids learn what they have a reason to learn.
If those three are in decent shape, your child is almost certainly getting what they need. And if one is wobbly — you’ve just found the exact lever to adjust.
Stop comparing to the wrong kid
The most anxious parents are always comparing — to a monolingual cousin who “talks so much,” or a picture-perfect bilingual family online. Both are the wrong yardstick. A bilingual toddler is doing two jobs at once; measured against a child doing one, they’ll always look a step behind. The only fair comparison is your child to themselves a month or two ago. Watch the growth, not the gap to someone else.
And yes — sometimes it is worth a closer look
None of this means ignoring a real concern. A few things are worth a conversation with your pediatrician or a bilingual speech-language pathologist, no matter how many languages your child hears: very few or no words (counting both languages together) by around age 2, not responding to their name, little pointing or gesturing, or losing skills they previously had. If that’s you, the answer isn’t to drop a language — it’s a proper evaluation from someone who understands bilingual development. Our free milestones checklist is a good gut-check to start.
Most of the time, you’re doing better than you think
For the vast majority of families I talk with, the honest answer is: keep going — you’re further along than the worry lets you feel.
And if what you really want is a person to look at your family’s specific setup and tell you honestly where you stand — am I doing enough? which lever should I pull? is my approach actually working? — that’s exactly what I built my 1:1 parent consultations for. It’s coaching and strategy from a licensed SLP (not an evaluation or therapy). Join the waitlist and you’ll be first to know when a spot opens.
