Hi Jaci,
With the 4:30 wake up and resettling several times, did she eventually go back to sleep for awhile or did you end up nursing her? My DD did that too during the first few nights... I'm not sure but I think it might be some 'learned' hunger that she was just used to being fed at that time. Once her body adjusted to eating properly during the day maybe that's why she stopped waking at that time? It's tough because it made me second guess myself, like does she have gas or teething pain, etc. But I think really it was just habit and once that habit was broken she was okay.
I see on your next post that she is not well today, maybe there was something to do with that. I am so glad that I am still bfing so DD can get the best nutrition when she is sick. And it is so comforting for them. I know when I am sick I still want my mom to come and take care of me, and I'm 30! hope she is feeling better soon.
