My baby is 38 days old. Im a little concerned about his feeding pattern. During the day he wakes up when he is hungry but when i breastfeed him he takes for 5-10 mins and goes to sleep and if i give him formula milk that also he drinks haf and goes to sleep. Then it becomes very difficult to feed him in sleep. At night also sometimes he doesnt wake up for 4-5 hours for feed.. What should u do??
