How do you make baby feel cozy in their crib? Even though my son is swaddled he wiggles around in his big crib and wakes himself up. I put two rolled up blankets on either side of him and he did better. I know having anything in the crib is a no no but I am trying to help him transition. I am watching him on the video monitor to make sure he doesn't wiggle down to where the blankets are.
