My daughter is 2 yrs 3 months old. Physical growth is gud so far. Only problem we are facing is she gives less eye contact. Whatever the rhymes she sees she is able to sing the same. She is able to pronounce very difficult words but she doesn't call me mom. She doesn't ask for anything when she needed. Any emotions she conveys through singing rhymes. Even while crying she sings Johny Johny yes papa. Is there a need to consult paediatrician?
