Well if nothing else works, give the dryer a try. It's something older people say to do and I never thought it would work, but we did it and it worked wonders

@jaxmomma never tried the dryer. We did a lot of car rides with our first and the swing of course but he doesn't really like the swing too much.

Have you tried the dryer trick? I thought my husband was nuts, but it really worked! My son was up until 3 am screaming from colic. My husband put him in the bouncy seat, turned on the dryer, then sat the bouncy seat on the dryer (holding it of course). The vibrations got out the gas and he slept 8 hours straight. He fell asleep after being on the dryer maybe 5 mins!!
