Highchair Stickers

I usually shower in the morning before my husband leaves for work, but he was out of town a few weeks ago and I needed a way to contain and occupy S while I showered.  I brought his highchair into the bathroom and gave him some stickers and paper.  He still has a lot of trouble removing stickers from the backing, so I peeled each one off and placed a corner of each one along the perimeter of the highchair tray.  He was able to easily remove each one to stick to the paper and I was able to shower!  Feel free to leave your shower-occupying tips in the comments.
