From about weeks 3-5, DD was not sleeping well at night. In the evenings, she was super fussy. I would feed her, she would fall asleep at the boob, I would put her down, she would cry. I would feed her again, she would fall asleep at the boob, I would put her down, she would cry...and the cycle would continue like that for a few hours. I could not figure out what was wrong - whether she had gas, intestinal issues, colic, etc. And once she got to sleep, she would wake every 2-3 hours during the night needing to be fed.
Well, when I started pumping, I noticed that my supply in the evening is about half (or less) of what I have in the morning. So, I had the theory that maybe she was not getting enough milk. Four nights ago, we started giving her a big ole' 6 oz. bottle of pumped milk as her last feeding before bed. She gulps the whole thing down and the results have been AMAZING. Now she sleeps for 4-5 hours and even after she wakes up, I do a feeding and she goes back to sleep for another 2-3 hours.
I could not be happier and I've felt so much better now that I can get some uninterrupted sleep. I know that all of our sleep problems are not solved but I feel like I crossed a hurdle so just wanted to share.
