Hello, My daughter is 4 and half months old... today while playing she was saying oooo and was busy playing (trying to keep her toys in mouth) and when I called her she didn't listen... I intact called her so many times but she was busy playing Is this normal ? I am having so much anxiety that she might be autistic... I am so much worried... she laughs.. smiles and do everything but I don't know why I am tensed.. She didn't not even roll yet even to her side... when does babies recognise their names ? And who gets autism ?
