My baby is 1month & 18 days old now. He’s attached to my breast whenever he’s awake in a day. He drinks my milk for a while & then he sleeps. & when I put him down on bed he again starts crying. Then I need to feed him back again then he sleeps again after few minutes of feed & then sleeps again. This keeps on going while day. When I give him formula then he spills it back after sometime. Is this normal in babies?? Am I overfeeding him that’s why he’s vomiting ??becoz he never says no to feeding.I feel exhausted whole day because of feeding. Can you suggest something??
