This is great! I have to admit that weight gain is one of my big worries with scheduled babies. A lot of times, the schedule will work at first, in the early weeks/months when supply is naturally high. But as time goes on and the body "reads" the infrequent demand and translate that into lower supply, weight gain can really slack off.Ped said she was good. She said she is gaining weight on a normal range.
If a baby is >6 weeks of age, is being fed on demand during the waking hours, and is gaining weight at a normal pace, it is perfectly safe to allow her to sleep through the night, even for crazy long stretches (e.g. 8-10 hours). It almost surely will not last, since most babies begin to wake at night again when teething starts (often as early as 3 months).Although I mention that I have to wake her up every day after the 8 hour feed because she wont wake up. That is the longest stretch and its during night. And she said that at this point I could let it go and see when she would wake up. First night she woke up after 9 hours, but today its been over 10 hours and she is still sleeping. I'm confused because they say "never wake a sleepy baby" but I don't know if this long stretch is ok. They also told me that eventually between the 2nd and 3rd month they could start going from 10 to 12 hrs of sleep. I understand every baby is different, but I want to know about healthy.
That being said, it is perfectly fine for you to proactively wake baby and feed her, especially if you are getting so engorged and uncomfortable that you can't sleep and you are resorting to the pump!!! If your baby is sleeping with a pacifier or is swaddled, taking away those sleep-extending tools may get her to wake spontaneously and relieve some of your discomfort.
One good reason to wake your baby to nurse at least 1x overnight is fertility. Once you're routinely going >6 hours without nursing, your prolactin levels will fall low enough for long enough that your estrogen levels will rebound, and that may trigger a fertile cycle. It means you need to be a lot more careful about birth control and it also means that one of the big side-benefits of breastfeeding, which is that many moms will not get their periods for months and months, may go away a lot sooner than you might like.
