So here I go, imparting all my vast mama wisdom (similar to a 1st grader telling you the secret to achieving academic success). Here's the recipe that seems to be the reason our baybee sleeps through the night.
1. When the pediatrician tells you to supplement with pumped milk because your baby has lost too much weight, completely disregard the amount she told you to feed your baby and cram her full of as much milk as she wants, even if she pukes half of it back up. This stretches out your baby's stomache and causes her to demand more milk, and also causes her to gain a whopping 12 ounces in 3 days.
2. When the pediatrician tells you you really don't need to feed your baybee so much, and that she doesn't need to gain weight so fast, you listen intently. You try to implement this, but now she has come to expect a lot of milk when she's hungry. Her stomache is stretched.
3. Try your darnedest to reduce the amount of milk required at each feeding, because your boobs just aren't that big and can't hold that much milk. Fail, utterly.
4. Adapt to the status quo. She feeds all day long, cluster feeding in the morning and evening. Since your boobs can't possibly produce milk that fast, you implement a power pumping session after she goes to bed so that you can have extra milk to supplement her during the day.
5. This baby stomache is now the Hummer of baby stomache's. Tough to fill, but since it allows her to sleep through the night, your baby is a status symbol that causes jealousy in other moms. Put her down at 9 pm, pump for a while for the next days feedings. Have a glasss of wine and watch your favorite TV show, knowing she will not wake until ~6 am.
P.S. Make sure to put her in one of the snazzy night time diapers before she goes down.
