Update on a sleeping boy

So the last couple nights Jonah has gone to sleep really easy. We do our bedtime routine - bath, read, pray, song, rock and cuddle for a minute, and then into bed with his blankie and thumb in mouth. Last night I had to go comfort him again about 15 minutes after putting him to bed because he got his leg caught in the bars of his crib (and started screaming), but other than that he was good to go. He's done that a couple times this week. He likes to prop his foot up on the bumper but sometimes I think he gets it too far and his foot goes between the bars of his crib. He turns just a little bit and his leg is stuck, thus the screaming. I'm wondering if I should line his crib with mesh so he can't pop his leg through the bars.
