Language Development 18-30 Months
What You're Child Should Be Doing

Language development 18-30 months: Your child uses speech and language that will surprise you on a daily basis.

At this age your child has learned A-L-O-T of words and phrases from you...

...now they will verbalize more.


When my daughter was 21 months old my wife and I couldn't believe how much she started picking up from us.

I'll never forget when my daughter and I went to get the mail one day. After we had grabbed the mail. She turned around and held up her arms pointing to the left and right of the street.

She then shook her head to the left and the right (it looked like she was saying "no") and said...

..."no ca-s" (no cars).

I had been trying to teach her to "Look both ways" for cars for 2-3 months, and then she spontaneously said it on her own. I was so proud.

Of all the stages of speech and language milestones 18-30 months is my favorite. Notice that some of them can happen after 30 months too.
