Thursday night, Aislynn would NOT go to sleep. she was up till almost 2 am (normally out like a light at 8pm). Then about 2am she vomited copious amounts of breastmilk. otherwise she seemed very happy, alert and normal. after her throwing up (and subsequent bath) she fell asleep.
Friday was mostly normal, ate normally, still very active and smiley. no vomit of note, but stayed up till about 10pm (I chalk that up to the messed up bedtime the night before.
Today, she projectile vomited on DH this morning. She ate normally throughout the day, but slept almost all day. seriously, like 3 naps of 3 hours each! She also only had wet diapers since friday afternoon, no poop. Ear thermometer read 99.7 and armpit temp read 98.4 (but that thermometer is a piece of crap) Then she woke up at 9:30 tonight and seemed very normal. Had a poopy diaper and I was thinking she was okay. she started fussing to I warmed a bottle of breastmilk, which she ate, but only got about 3.5 oz before she SPEWS everywhere. I mean it looked to be way more than the 3.5 ounces she just ate, and she hadn't eaten in 4 hours. I cleaned her up and she fell asleep again.
DH says let her sleep it off, but I'm wondering if I should try to go get some pedialyte or something. In spite of the vomit and excess sleep today she really has been VERY happy and normal while awake. Not at all listless or cranky. (she's never really a cranky baby).
anyway, just looking for some BTDT opinions on whether this is something that sounds serious or if I should just let her sleep it off.
