My daughter is 2 yrs 8 months old but she is not speaking much. She always tells first one or two letters of a word just like, if she wants to drink water, she just tell "wa". similarly she says lion as "li", tiger as "ti", ball as "bo", cat as "ca" etc. She can understand what I am saying. If I tell her to say word completely, she just ignore me. She do not want to follow our words. But she can say some word like "papa", "shoes", "go", "come" etc. We do not understand what is the problem. Do we need speech therapy for her? Please suggest us.
