Good morning) My daughter is 2 months old. She always falls asleep almost at 12 midnight. She used to eat around 3-4 and then at 6-7 in the morning. For 4 days now she's been sleeping only at 6. I tried to wake her up at 3-4 to give her a breastfeed, but she wouldn't take it. Her dad skips this feeding. Even though I get some rest with her, it's really stressful. Is it normal for such an age to hold out for 6 hours without food? Does anyone else have this problem? Please share if you do.
