Don't worry about it... my son just turned three and only had about a ten vocabulary until just recently. He is now speaking full sentences. As lomg as she understands what your saying, I wiuldn't worry.
My son is 19 months now and he is not talking. He has said Mama over the last 4 months but very rare and far between. I am wondering if I should get him evaluated because everyone else seems to think so. He communicates but in his own language! I would like to know your son's progress, seeing how you wrote this 3 months ago.
Don't worry about it. I had the same questions too when my son was 18 months old. Just said Dada. I had people suggest speech therapy. I just ignored it and now at 27 months, he won't stop talking and he picks up things you say (so be careful what you say!). Every kid does their thing at their own pace.
My granddaughter is the same way. She isn't talking much or at least I'm not understanding the words she is trying to say to me at times. she babbles when she's reading a book and like your child she knows commands and can retrieve and do anything I ask of her. She lives with me so I have gotten to know many words that she is speaking. Our dog Daisy, she calls day day, and also can say kitty cat but I don't know if a stranger would understand what she's saying. Other then that, she is very bright and has been early on all other milestones. Also she does say the amount of single words that an child of 18 month should know by now. Good luck to you and try not to worry, her doctor doesn't seem to be worried either..
Hi Mom, this is more common in a child with an older sibling. The question you might want to consider is this...does the older sister do the talking a lot for her and not let her speak for herself? Also I would try encouraging her when she points say "Use your words." This helped out my neice. She is older now and doing just fine, she did have to go into speech therapy at 5 but it was very helpful.
