M.K.
What I did with my little guy was let him sleep in a swing. About a month ago (4 months) he showed signs of actually wanting to go to sleep, he snuggles. When he gets like this I started putting him in his crib or laying him down in a "pack and play" in the other room. He slept fine. Before this he would sleep in the swing and car seat and it didn't ruin his ability to sleep in a crib when he got older at all.
The swing "coaxed" him into sleeping when he was fighting the sand man. But now that he is a little older he lets himself fall asleep easier, hence the ability to fall asleep without movement.
Good luck!!!
