Fits in the top rack!
We tried this plate out yesterday. And I do mean "we," both the baby and I! I stuck it in the top rack of my dishwasher (yay dishwasher... and freezer, and microwave, and OVEN safe!) and it FIT! I thought that was awesome! So many kids plates just will not fit on the top rack.
When it came time for dinner, we put it to the test. Tiny is at the phase where it is fun to throw things from the high chair, even if they taste good (bye, bacon). She tossed her bacon, eggs, and French toast down bit by bit, occasionally eating a bite, but the plate remained! Yay!
