hi.. my daughter is 33 months old now. but she is having delay in speech. she communicates less when compared to child below her age. 2 year old kid was able to communicate much better than her. she is very good in telling numbers till 20, a-z with words, days of the week, and many rhymes but she is not making communication like a 2+ yr old. this worries me a lot. Is this sign of autism?
