breastfeeding newborn

Charity

so my daughter was just born on 3/14/18 and she's been doing amazing with breastfeeding. she started cluster feeding yesterday towards the end of the day and into the wee hours in the morning today. now she will barely eat for 5-15 mins and be done for an hour or so, sometimes even up to 3 hours. is this normal? my first child was in the NICU for 2 weeks so this is all brand new and idk what's really normal right now. thank you!
