Giant Connect Four! Take a shower curtain, spray paint it yellow and leave "holes" for the game pieces. Grab some plastic plates from the dollar tree and throw on Velcro on the back of the plates and where the holes are, then use Velcro to hang it from the wall each time you want to play. Kids loved it!
Felt Quiet Book Bathroom (Take a Shower) Page with Felt Doll. It is possible to open and fix the shower curtain and insert the felt doll into the bathtub. This is one of the pages I made for Mila's quiet book. This one is my favorite :)
