Gasiosis of the mostest

I noticed today (technically yesterday because it's past midnight, but the date would be oct 17, '11), during small group that Paul had major gas problems. I mean I had noticed it before throughout the day but hadn't thought of it being anything other than just gas. But it was/is, in fact, a bad case of gas. I had to keep checking him for poopy diapers without there actually being one.
But we've just got him down for sleep and I'm sure I'll be up very soon comforting him again.
We have done our best to do everything we can think of to help remedy him, but only time will tell on this one. We have swaddled him and are playing white noise (was a combined effort at first of cellphones, radios, and the monkey. But we are down to just the monkey now). We also gave him a treatment of gripewater, so hopefully that will keep his stomach calm. Like I said though, only time will tell. The only thing keeping me awake now is the nagging question of; what did I eat today or yesterday that has given him such painful and stinky gas?
