My little girl has horrible reflux. She quite often vomits if she's on her back. Usually comes out her nose and she goes rigid and screams. I'm told it's usually something that goes away in a few months, but if not, it could be a fairly difficult thing to deal with. I'm seriously considering that video game solution though. I do normally get up at 5:30 or so to get ready for work, so it might be a situation where I get up at 2AM instead and just sit there with her and game.
I hope she gets better soon. It can take a long time as it did with our son. Since I'm seeing a chiropractor weekly anyway we got him to go along on a discounted plan for the first 3 years. That helped with his digestive tract. Putting him in bed was not really an option, just screaming in pain and all rigid. It was so bad a lot of his baby teeth rotted from the acid and they had to put him under at the hospital to fix his teeth. He's all better now, still a very picky eater yet doing great otherwise.
Hopefully I haven't turned him into a psychopath after many long nights of Dark Souls with him on my lap :)
