Yesterday while giving Preston a bath he kept insisting on standing up - which isn't unusual. I think I sternly said "Preston, sit down!" about fifty gazillion times.
Preston would start to squat then stand back up. Squat. Stand. Squat. Stand.
Finally I realized the CLEAR funnel he plays with in the tub, was directly below him under the sudsy water...and the pointy part was sticking straight up.
Clear tub toys...so not the way to go.
