Sleepless nights

Britt

My 2nd daughter is almost 4 months and sleeping at night is so inconsistent compared to the first time. The night before last she woke up every 2 hours 🤯😱😵😴 and last night slept the longest ever 8 hours 🙆. I'm really struggling getting my sleep because regardless if she sleeps more than 5 hours, I get up every 3-5 hours to pump or feed and going back to sleep is my biggest struggle. Any tips welcomed... Has anyone used melatonin while nursing???
