When LO goes a longer stretch of sleep at night she'll eat a lot when she wakes up (I have a really strong letdown) and have an upset tummy for a while. Usually once a night she struggles and then poops a large amount. This seems to be the biggest hurdle to getting her back down, because she'll be very sleepy but wake up grunting. She's 6 weeks today. Anyone else have this problem, and if so when did it get better? She almost never spits up, just a good pooper.
