my baby is 5.5 month and from 10-12 day he is getting very irritable and fussy when he falling sleep... is this normal or should I worried about this?

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 due to nasal blockage or some body pain wshich might be initiation of a viral fever also. you have to treat according to the findings so better to visit a doctor. z
