Hello! Could you please tell me, my baby is 10 days old, he sleeps not very well during the day for about 30 minutes, outside for 2 hours in a stroller. I bathe him at 9:30 PM, and by 10:00 PM we eat and fall asleep by 11:30 PM. Here it's 6:20 AM, but he's still sleeping. For a couple of days I wake up myself to feed him around 5. Is it normal that the baby sleeps so long at night?
