hi, i am worried for my grandson,he is develping well,regarding what thr dr,said he is 17months old walkin,but i dont see a happy baby he is fussy cries a lot not a single word yet but screams loud,very short eye contact ,doesnt point,or wave bye,uses his pacifire to calm down,doesnt like to sit on your lap or even hold your hand when he walks,seems hyper at times restless.
