Re: DS can get out of his crib!!
I think your solution works wonders. It isn't safe for him to continue to climb out of his crib, especially if he is sleepy. My little guy loved sleeping on his crib mattress on the floor for months (even though he had a twin bed right beside his mattress). I guess he just felt it was too big. Good luck. I remember the worry, but seriously it passes so quickly. My little guy felt like such a big kid!
