Hello, from last 1 week, my 7 month son awake in mid-night and start crying without tears (normally he cry with tears) and do not open his eyes. He takes milk between 11pm - 12am but still awake and cry between 2am to 4am. He is not taking sound sleep. Please help

A. Crying of a Baby is mostly because of infantile colic and gas related discomfort which can be relieved by medicine like colicaid /gastica drops. other reasons could be nasal blockage, eart pain, diaper rash and more which needs to be ruled out and managed accordingly .
