Bless your heart! I know where you're coming from. Our daughter had colic and it was crazy for a awhile there. She settled down at night at about 9 weeks - but still cried for several hours during the day and wouldn't/couldn't nap much. It's probably all related. Here's what we did:
1) Mylicon is your friend! The gripe water never worked for us - so we just stuck with mylicon. However, you can't wait until the crying starts - you need to get out ahead of it. Give him a dose of mylicon with each meal and before bed if he doesn't take a bottle at bedtime. (this was recommended by our pediatritian and it's perfectly safe).
2) Another tummy remedy - it generally shows signs of working about 10-20 minutes after you do it. Lay him on his back and move his knees into his chest/belly one at a time for 5 times each leg. Then do them together for 5 times. Then rub his tummy in clockwise circles for a minute. Then move his knees into his chest and gently rotate clockwise for a minute. He'll probably calm down by the time you're doing the last part, and will start passing gas shortly after.
3) Warm heat on the tummy - wet a washcloth and put it in the microwave for 15-30 seconds. It should be very warm but not super hot. Put it in a ziplock bag. Then put it on his tummy on the outside of his clothes. You can also wrap it in a dish towel if it seems too hot. Just don't put it directly on his tummy.
4) Swaddle. Yes, there are people out there that say don't swaddle after a couple of weeks. And I say that these people never had a colicky infant! Anytime we put Jordan down for a nap or to sleep at night, we swaddled her up tight.
5) Rock. Rocking is always good. But if you have a glider with a gliding footstool - use that. We used to swaddle her up, put the heat pack on the glider footstool and put her tummy down on the footstool and just rock her on that. The swings that go sideways work wonders as well. They are not cheap - but are worth the peace!
6) Moses Basket. I'm not sure if you have him in a crib or bassinet or what. But we used a moses basket for the first 7-8 weeks becuase Jordan seemed to need the more close feel of it. I think the crib was too big and scary for her. We continued to use the Moses basket for naps up until she was about 4 months old.
I hope some of this helps! Good luck!
