How much do your 20 month olds talk? My son definitely understands what we're saying when we talk to him, but he still doesn't say too much. He is starting to say "dada" and "mama" but doesn't really associate them with me and my husband. He babbles a lot, but doesn't really say words. He's definitely smart though - he can clap and tries to imitate what we do and he can do a whole alphabet puzzle by himself with no problem. He doesn't go back to the doctor until his 24 month appointment. Should I call to talk to his doctor now? We talked the the girls that take care of him at daycare and they don't seem to be overly concerned at this point.
Re: 20 months and not talking much
I will share my personal experience with you. My son is almost 20 months and since about 15 months all he has been saying is Mom, Da, ugh-oh, and a few animal sound effects. I decided to wait until 22 months to call EI if I don't see much improvement hy then. I have a feeling his language explosion will happen soon and I won't have to call. In the past few weeks, he has starting saying "here" when he hands me something, and has added turtle and car to his vocabulary. Then there are occasional words like door and button where he will repeat a few times and then I never hear them again, so I don't really "count" them since they are not consistent.
Remember, boys are always slower to talk, so just be patient, yet proactive if you ultimately decide it's necessary. Lots of reading and repeating words can help in the meantime.
