Do you swaddle them? If not, you might try it. I found it especially useful when tranferring from my arms to the crib. Wrap them up before you rock them to sleep. Then the swaddle keeps their arms and legs from flopping around while you transfer to the crib, and keeps them feeling warm and toasty. Pretty soon they'll be strong enough to kick out of the swaddle when they wake, and that's fine. The swaddle is just for the transfer to the crib at this age.
