Just did this and wow am I ever glad I did! The pack 'n play looked virtually unused but the water told otherwise!! I used homemade laundry detergent, vinager and a bit of burts bees baby shampoo for a fresh baby scent.
Puzzle storage!! Best way to store kids puzzles! Buy some Legal size poly expandable envelopes. Remove the string and replace with Velcro circles. Place in a bin or on a shelf. My rule is one out at a time. The envelopes are easy enough for my two year old to open and clean up himself.
