Yeah you have to let him cry for two reason. The first is becuase, if you pick him up every time he cries he'll get used to that, and when he is older he'll expect everything when he cries for it. And the second is that he can't sleep with you. I know a lot of peopl co sleep, but it is not good for the baby. Just the other day they had a show on cable access, that had like 12 mothers and some father, who infants had dies because of it. I don't have children, but I know about crying ones. Let him cry and cry, he will cry harder but as long as nothing is wrong, just leave him alone. He'll wind up cying himself out, and fall asleep. All babies do it, and I still do it, like when I cried because a dog got shot on tv the other day, I started thinking about my dog a people and I just cried harder and harder, until I fell asleep. And my doc says that advent bottles are good, they are supposed to be like the breast (the ones that are soft inside), and because it doesn't hold air, there is less gas.
