I think LO is going through her 4 month sleep regression. She went from sleeping 10-12 hours to 7-9 hours. I have been feeding her when she wakes at night and I'm wondering if I am creating a middle of the night feeding habit. (Coincidentally, she started waking up a day or two after I stopped the 2am pump session, so still waking up in the middle of the night!) I'm looking forward to her 10-12 hour sleep stretches again!

What was your LO's 4 month sleep like?
