Swaddling efforts

We are swaddling Micah when he goes down at night because it helps him sleep longer and more soundly with his arms not flailing around.  Last night he wasn't quite asleep when he was put in the bassinet, and as Christian and I are falling asleep ourselves, we kept laughing listening to our little boy.  He would randomly make these whimpering sounds every 30 seconds or so for about 5 minutes, which is when he was trying with all his might to bust out of the velcro-bound swaddle.  Although he has been successful in the past, thankfully he settled down last night and went to sleep.
