The only problem my daughter had was the open space in the crib, she was sleeping in a bassinet next to the bed which was much smaller. So when we put her in the crib we put one of those sleep positioners in with her (even though she didn't need it anymore, she can turn over and what not) it helped her feel like she wasn't alone or in this HUGE empty space in the crib. Its been a few weeks now and she does fine without it. Also when they cry (if your BFing) if you pull them out of the crib put them straight on the boob, that way they know that the one reason the get to get out of the crib AT NIGHT is for food. If you have fed them and put them in and they haven't fallen back to sleep then but your hand on their chest for comfort and stay there until they do fall asleep (caution: it can sometimes take A LONG TIME) but they will get used to it. Obviously if they are screaming bloody murder DONT LEAVE THEM. Hope it helps.
