What is the feeding interval at 3 months old? My child can walk 5-6 hours without being fed. For example, today at 5 pm I fed him and tried to feed him at 8 pm, but he doesn't take it at all! ??? He only takes it now at 11:42 ??? Why? What could be the reason? We are exclusively breastfeeding. We don't drink formula. But at night he hangs on the breast. But during the day, feeding is a big problem. The mouth is clean, there is no stomatitis, nothing. There is no tonsillitis. It has been like this for a week. And before it was okay.
