Hi, my child who is almost 36 days old is taking milk regularly but not sleeping for past 2 days. After every feed when he make him sleep, he automatically wake up after 5-10 mins and start crying and chew his hand. We are giving him breast feed and formula milk both in sufficient amount still ask for more milk by chewing his hands or bib. Also giving colicaid on daily basis. Could you suggest what must be the problem is
