The pack 'n' play has been such a godsend even more with Luke than it was with Sam. We love knowing the with just a few toys in there, Luke is safe to play and crawl and move about, even when Sam is around. Sam loves to hang outside and talk and play with Luke but we know they are both safe, which is great! The best is when Luke presses his little nose and face on the mesh sides....so funny! Thank goodness for the pack 'n' play
