Baby 5 days old sleeping for 8 hours without feeding (1st time) born at 37 weeks, slow at nursing but was told to expect that, is this normal?

Let baby set schedul: Any baby that is well hydrated can be left alone to sleep as long as 8 or more hours. Their intestines has food they are continuing to digest ; use during this period ; if baby can deal with it ; thrive there is no reason to wake her.Babies don't sleep more than 4 hr without cycling to a lighter sleep state so the fact that yours can settle back ; sleep longer is wonderful.

TERM INFANT: 37 to 42 weeks is term pregnancy. Newborns sleep 18-20 hours a day. Feeding is needed every 3 hours on an average, night time gap can be 4-6 hours max. So wake the baby by gentle movement/ rubbing the back and offer feeding. Too much sleepiness combined with refusal / poor sucking, poor muscle tone, pallor, moaning, hypothermia are signs of infection. If these happens, talk to the pediatrician.
