If she's gaining consistently then let her sleep If she's gone from waking 2 hourly to a 7 hour gap, I'd guess she wasn't waking out of hunger, but habit. If you know she normally lets you know when she's hungry I wouldn't stress...but keep an eye on her weight gain just in case. At this age I'd try 4oz at a feeding and see how she goes. Feeding every hour and a half during the day is very frequent...ideally (haha that's funny) you'd be expecting 2 decent (2-3 hour) naps during the day. Sleep encourages growth

Good luck!

My 35 weaker started sleeping through the night at about 6-8 weeks. He was not yet 10 lbs at that time. He still sleeps all night and has not had any problems. I say enjoy the sleep!:)

If your Peds nurse thinks it's ok I'd go with that!! If she's drinking formula it stays with them a little longer than BF babies. But, my BF 37 weeker was about 11-12 lbs at 5 months when she started sleeping through the night 11-12 hours straight through. She was my one and only to do that - I should have enjoyed it more!!

My daughter (born at 35 wks due to severe PE at 4 lbs 9oz) has been sleeping through the night for the past three nights (10pm until 5am). She is 3 months, two months adjusted weighing just over 10 lbs. Up until the last three days, she woke every two hours for feedings. During the day she eats 3 to 4 oz every three to four hours (mostly a two oz bottle every hour and a half). I called my peds office, the nurse did not seem concerned, but my nerves still won't let me relax. I know that being healthy does not mean that she has to be above the 50th percentile by any means...but should I wake her up for middle of the night feedings?
