First off, I just want to say thanks so much for all of your advice...It has helped me through some rough patches these past few months. Anyway, my LO is 3 and a half months old and she has been doing very well with BF all along. Just this past week, she's been having a bit of a hard time and I can not figure it out! To begin with, Saturday, my husband and I had a wedding so we left her with my sister for the first time overnight. She had breastmilk the whole time, but it was in a bottle. During the day I guess she ate 5 oz at a time and at night she at about 9. (I pumped about 4 times while I was away from her) Ever since leaving her, she has been latching ok and seems to be eating, but halfway through and at the end, she pulls off and starts screaming...almost like she is not getting enough. Then she tries to latch again and pulls off 3 or 4 more times and just cries. This has mostly been happening in the evenings more so than during the day. Also, to add to it, I started the mini pill on Sunday and I am wondering if that has anything to do with it. She also had been sleeping about 10 - 12 hours a night with no disruptions and this past week, she is waking about every 2 - 3 hours. I have tried feeding her, but it doesn't seem to help. She usually finds her thumb to suck on and falls back to sleep within 5 - 10 minutes, but it just is so not like her. Also, up until this week, she was such a happy baby (smiling, cooing etc) and this week, I've had a hard time pulling smiles out of her. Sorry for such a long post, but I'm really concerned and wanted to give all the details so maybe someone could give me some suggestions. Another thing too is she is not running a fever and has been drooling a lot...could this be teething? I know it is early and drooling doesn't always signify teething, but the fussiness and stuff is so strange for her. Thanks in advance for any advice you can give me! I really appreciate it!
