I am aware of the tipping issue, believe me. I've got one little girl that I think intentionally spills her bowl. I've got a heavy ceramic ramekin in there right now, and if I don't tape/velcro it down it'll be tipped over every morning. I'll be using either the PVC couplers velcro'd to the sides or velco'ing one of the bowls down and placing a second bowl with the water inside that...
