My 2 year old son is not talking. He says 3 words (thank you, Spongebob & look) but not even mommy or daddy. He will be 3 years old this November 19. He will point and make a whimper like sound for something he wants to communicate, but if its something he can't have it will get ugly real fast. He will throw a fit big time. Since he does not talk its hard to communicate rules to him. He does not seem to understand of doesn't care to listen. Mostly I try to avoid things that I know will set him off. That will work some of the time but there are times when I just don't know how to handle him. He has had regular check ups from his doctor and is a very healthy boy. I am not sure whether I should worry about his behavior or let some time go by and realize that when he is age 3-4 he will start to do better with his communication. He is very loving and has lots of energy (climbs anything, jumps on furniture, plays in the pool, runs & plays ball....100% BOY) but his temper tantrums and not talking are really hard to deal with. Also his older brother is 12 and went threw a similar pattern with delay in talking and bad temper tantrums but by the time he was in first grade he was caught up and his temper calmed down. He is an honor roll student in the 6th grade now. So maybe this is a pattern in my family? Or should I be concerned and reach out for help for him. What could be causing it?
