hello doctor.. from today afternoon my baby is rejecting bottle, he is crying a lot while bottle inserting in his mouth. I don't know why this is happening

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, ear pain, diaper rash and more whicfh needs to be ruled out anxd managed accordingly .
