Not all babies like the arms wrapped in. I personally know 2 babies who even as newborns (even at 4 days old) would wriggle around for up to 3/4 hour before they went to sleep when they have exhausted themselves. When their arms were loose when put down for a sleep they would be asleep within 5 – 10 minutes. In fact one of them slept with her hands up level with her head.
