I have to admit, I've always been a proponent of crib sleeping as I think it helps the child to be happier when they can soothe themselves to sleep. But, I also have to admit, in the quest for rest, I have let my babies sleep with me until they were ready to cry it out. So I guess I am half and half on the issue. I did use a side sleep baby holder for safety, as I didn't want the baby to roll, but I've noticed they've come out with NEW products, to help with baby safety, like this "By your side" sleeper.
Still, I think the sooner the baby can sleep on their own the better, as the older they get, the harder it is to wean them from this practice. It's worth a little crying now, to avoid a HUGE battle later. And my babies were always happier when they could do it themselves.
However, I know there are babies out there with stubborn temperaments, so each family must decide what's best for them.
