Don’t cry over spilt milk. Fine, but it still ain’t fun cleaning it up. How hard is it to keep cups upright? Apparently, VERY! Instead of tipping over, the wide base will make the cup slide. The entire cup is designed for a tot, including the ergonomic grip and BPA free materials. It is also dishwasher and microwave safe. I am replacing my entire cupboard with these Baby Bjorn cups!
