PLEASE HELP ME TOO! I am in such a similar situation with my almost-10 week old, though with a few differnces. So...I'll fess up: I'm a pediatrician, and when my sweet baby girl started profusely spitting up and occasionally screaming in pain first at about 3 weeks of age, I told myself it was just infantile reflux, and that it would get better. And, it got much, much worse, until she started wretching and actually vomiting (including out her little nose). As her pediatrician was out of town, I spoke with one of my friends, a peds GI doc, and he said, "Why aren't you treating your poor baby?" She's been on Prevacid now for about 2 weeks, and it has definitely improved her daytime symptoms.
Here's our dilemma: we bedshare, and she won't sleep anywhere else. (So much for the $300 on the co-sleeper...an expensive laundry basket!) Lily simply won't sleep unless she is snuggled right up next to me, with her head resting on my breast. Getting her to sleep at bedtime isn't the problem--it's keeping her asleep. She nurses down, and then wakes up about 1.5 hours later writhing, groaning, and "hitting" me and herself, followed by a big ol' vomit. She is then completely alert and awake; I have to get up with her, and try to soothe her without nursing, (which just exacerbates the cycle of puking), and we finally fall asleep about 1-2 hours later, just to repeat this again in another 1-2 hours. I'm exhausted.
I'm thinking that this is happening at night because it is the only time she is actually flat on her back. During the day, she is in the Moby, my arms, or her swing, and is generally upright. Does anyone have any ideas of how we could continue to bedshare with her snuggled next to me, but with an incline? (I feel like the whole head of our bed should be elevated, as I don't want her falling off a normal sized wedge pillow that spans only 1/2 the bed.) I just have not been able to get her to sleep in the co-sleeper, (which I could use a wedge and elevate the HOB), and I'll admit that having her snugggle with me is one of the highlights of my day.
I'm also struggling with trying not to get too anxious about this. I keep worrying about underlying anatomic anomalies that would cause recurrent vomiting, and I have to keep telling myself that this is still likely reflux disease, and nothing that requires testing or surgery. Yeah, I'm a mess!
