Leaving the Toilet Seat Up
Some little boys (and men) have a particularly hard time remembering to lower the seat. Tape a cartoon picture of a toilet at eye level near the sink to remind him not to skip that step. Make a chart below, and have him put a sticker on it for every time he remembers. Give him a special reward that he’ll look forward to for every ten stickers, and soon, putting the seat down will be something he does automatically.
