Re: DS can get out of his crib!!
We have a crib tent. It is the Crib Tent II so I feel that it is safer since goes under the mattress. It has helped us (although we don't use the crib very frequently since we co-sleep) but it is nice to have when we need it. We made a big deal when we put it on and call it the "Princess Tent" and she asked to go in it because it was so exciting to her. Good luck.
