Hi all, am I the only father in here???

My wife and I just had our first baby boy, Riley, on 28 December 2009. He's had the colic, and the acid reflux, since he was just a few weeks old. Unfortunately we didn't think to try the swaddling until he was nearly 8 weeks old. Those first few weeks were rough. We tried having him sleep in our room in a bassinet, in the bouncy, in the swing, but he just would never sleep. Finally we just had to put him in the crib in his room and he had done pretty well the past couple of months.
For the past 6-8 weeks now, since we started swaddling him regularly, he's only been waking once in the night, usually between 2 and 4. However last week, he slept through the night nearly every night. For some reason, though, this week he's been waking in the middle of the night again. We thought he might put himself back to sleep, but it just hasn't happened, so I've gone back to the night-time feeding.
Since my wife is at home with Riley all day while I'm at the office, I try to help when I can at home. I'm pretty much the one who gets up for the night feeding, have been for at least 6-8 weeks now. There was a little stretch a few weeks ago where he would scream ANY time I tried to feed him. Only momma could console him and feed him. I felt so useless.

It was difficult, though, because she doesn't swaddle him as well as I do. But lately he's been getting better about that, except once last week when she went out with a friend, and baby cried the WHOLE time she was gone (other than a 30 minute snooze). He wouldn't calm down, wouldn't take a bottle or anything for nearly 4 hours.
So now (he'll be 4 months old next week) the issue is that the kid can't sit or lay still for one second, it seems, without fussing. He's usually okay if you sit there with him, hold him, bounce him, talk to him, etc. but as soon as you put him down, he goes nuts. It's really taking a toll on my wife since she is with him all day. I want to help, but not sure what I can do. Tonight I tried to make dinner (I cook most nights, yes I love to cook

) so I set Riley in the bouncy in the kitchen while I cooked while momma took a break. Fussing ensued, followed by screaming. I had just fed him a few minutes before and thought he would take a little nap, but no dice.
Well I decided to lay him in the crib for awhile. We needed a quiet dinned for once, and we're thinking he needs to learn that he can't have his way ALL the time. I figured he would stop fussing and fall asleep eventually. That didn't happen either. When we went in there after dinner, he had spit-up or acid reflux or something all down his back and was laying in it.

So now momma feels guilty for letting him cry like that, but at the same time she simply cannot hold him and entertain him 24/7. What should we do? He's scheduled for his 4-month dr appt. next week so I guess we'll talk to the doc about it.
OH YEAH, we've been using the muslin swaddling blankets for several weeks, but he always breaks out of it. So we use that in combination with a "swaddler" that has a flap for his legs to fit into, and wraps around him with velcro tabs. That helps keep the muslin wrapped around him, but he still usually works his way out of it by the time he wakes up in the middle of the night or in the morning.
