My baby is 4.5 months old, from past one month he is breastfeeding only when he is sleepy, while awake he rejects breastfeeding if I try to do so then I need to roam in swinging state & making him drink milk otherwise he is too much cranky & starts to cry and don't turn his head towards breast. He became normal after 10 days earlier but again he started doing so. Is there any health issue ? Why is he doing so? Please suggest🙏
