Baby wont sleep in crib

Ciera

Any mommies have babies that slept fine in the crib and then just suddenly didnt? My little one is almost seven months old and for the past couple weeks, he wont sleep in his crib at night very long. Before, we really didn't have any issues. He might fuss if he wasnt asleep sometimes, but I would just pat him and he'd go right to sleep. I could also put him in drowsy and he'd go to sleep. Then I had to make sure he was in a deep sleep and sneak him in. He's been a little sick, so I dont know if that has something to do with it. Any tips on getting him back in it all night without just letting him cry it out? I cant have him keeping the whole house up. Any tips would be appreciated!
