from last few days my baby is not as usual or normal.maximum time he used to cry. I think he has cough and he sleeps only on lap or movement

A. if the child is crying at this age it can be due to either teething pain or it might be a part of colic pain due to some digestion problem or it might be dude to nasal blockage or some body pain which might be initiation of a viral fever also. also look for fevxer, oral ulcer, insect bite or skinrash and allergy. you have to treat according to the findings so better to visit a doctor.
