Bye bye cradle

Skyla has been napping and half way sleeping in her cradle for the past 6 months .. but last night I caught her standing up in her pack n play (it's up high in the bassinet phase) so now we have dismantled the cradle, and Charles is putting her crib together in our bedroom right now and I have to lower the pack and play to the lowest setting. When I turned around last night and saw her standing (arms and legs locked) with half of her body above the rail of her pack and play I about had a heart attack.
