Hi - just happened upon your post tonight.
Couple of things - white noise works great in our house - how about a fan? We have one inside a hamper, tiny little fan, locked the hamper:) so that the air doesn't circulate much around the room and make ds cold, and the lock is obviously so he doesn't get into it! (quite a bit older than your lo).
You mentioned reflux - what makes you think that, other than the bad sleeping? (which of course IS a possible symptom...but lot's of lo's have bad sleeping issues!)
If your lo DOES have reflux, crying for hours, even many min's on end will make it worse :cry: .
Can you post what you think the symptoms are, and any schedule you have your lo on, and we'll take a look at it together?
Also, if you go to the Colic/Reflux and Crying board, there is a post called Reflux 101 that lists the symptoms of reflux. That may be of a bit of help.
