Do you wake your baby to eat?

Erin

My daughter is 17 days old and will sleep in 5 - 6 hour stretches. I have been setting an alarm for every 2-3 hours but I slept through it once and she slept 5 hours. At her 2 week checkup the doctor said she’ll most likely wake up at night to be fed and that I don’t need to set an alarm. Well she just slept 6 hours.

Should I keep waking her up? What do you do? I’m liking sleep but I don’t want her to be hungry. She’s gained 12 oz since birth.
