Query: Agree with other reviewers...bowls don't stay put

I got these when my son was 12 months old and already a strong little guy who enjoyed dumping his bowls of food onto his high chair tray. Trying to outsmart him, I purchased these hoping to keep some food in a bowl. Much to my disappointment, they only stick to the formica countertops well. The littlest one doesn't even stick to that. None of them stays on my son's plastic high chair tray for more than a second or two.On the upside, the lids are secure once shut all the way (which can take a little work), so they make great storage for on-the-go finger foods in the diaper bag...I haven't had one leak yet, and I put things like applesauce in them to test them. Not a total waste of money, now that I found this alternate use. They wash well, without any noticeable breakdown of the plastic, on the top rack of the dishwasher.
