my baby is 10 month old & from last 2-3 days in night he cries a lot like some pain or irritation. what could be the reason?

A. if the child is crying at this age it can be due to either teethincg 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 wchich might be initiation of a viral fever also. you have to treat according to the findings so better to visit a doctor
