My 2-year-old only says single words. Should I worry?

By around 24 months, the CDC notes that many children say at least two words together, so single words alone is worth mentioning to your pediatrician. It does not automatically mean a problem, since children develop at different rates. Your pediatrician can do a developmental screening and suggest next steps if needed, and acting early is recommended when you have a concern.

What age should I start toilet training?

The AAP suggests starting based on readiness signs rather than a fixed age. Some children are ready before 2, while many are closer to 3, and both are normal. Watch for signs like staying dry for a couple of hours, sitting on a potty, and telling you when the diaper is wet, then talk with your pediatrician about timing.

My child is meeting most milestones but not all. Is that okay?

Yes, this is common, because milestone lists describe what most children do at an age, not a strict checklist. Children gain skills at different times, and missing one item is not the same as a delay. Keep tracking your child's progress and raise any specific concerns with your pediatrician, who can decide whether further screening is helpful.

2-year milestones (CDC): phrases & toilet readiness

At about 24 months, many toddlers start putting two words together into short phrases and begin showing early signs they may be ready for toilet training. The CDC's developmental milestones describe what most children do by this age, and the AAP suggests waiting for readiness signs rather than a fixed birthday. Children vary widely, so use these as a guide and let your pediatrician confirm what is typical for your child.

Language milestones around 2 years

By 24 months, the CDC notes that many children point to things in a book when you ask, say at least two words together such as 'more milk', point to at least two body parts when asked, and use more gestures than just waving and pointing. Vocabulary is growing quickly, though clarity still varies and not every word will be easy to understand. Following a one-step direction without gestures is usually seen earlier, by around 18 months.

Two-word phrases are a key signal at this age because they show your child is combining ideas, not just naming objects. If your toddler is not yet putting two words together by around 2 years, mention it to your pediatrician so any concerns can be checked early.

Says at least two words together, like 'want snack'
Points to things in a book when named
Points to at least two body parts when asked
Uses more gestures than just waving and pointing

Other things many 2-year-olds do

Beyond language, the CDC milestones for 24 months span movement, play, and thinking. Most toddlers are walking and starting to run, can kick a ball, and play alongside other children. Many can hold something in one hand while using the other hand, and notice when others are hurt or upset. Pretend play, such as feeding a doll, often appears a bit later, around 2 to 2.5 years.

These skills appear at different times for different children. The point of the milestone lists is not to grade your child but to help you and your pediatrician spot anything worth a closer look.

Kicks a ball and runs
Holds something in one hand while using the other hand
Tries to use switches, knobs, or buttons on toys
Plays with more than one toy at the same time, like putting food on a toy plate

Signs of toilet readiness

The AAP advises starting toilet training based on signs of readiness rather than a set age. Some children show readiness before 24 months, while many are not ready until closer to 3, and that range is normal. Pushing too early often makes the process longer, so it is usually easier to wait until your child shows several signs.

Readiness is a mix of physical, behavioral, and language skills. You do not need every sign at once, but a cluster of them suggests it may be a good time to begin.

Stays dry for a couple of hours at a time
Can walk to and sit on a potty
Can pull pants up and down with some help
Tells you, or shows, when the diaper is wet or soiled
Shows interest in the toilet or in wearing underwear

How to use these milestones

Use milestones as conversation starters, not pass-or-fail tests. The CDC recommends tracking your child's development and acting early if you have concerns, which usually means talking with your pediatrician and asking about a developmental screening.

Growth follows broad ranges too. WHO child growth standards describe healthy growth across populations, but a single number matters less than your child's steady pattern over time. Your pediatrician looks at the whole picture before making any recommendation.
