As a parent I tend to be obsessively concerned about design. We were at the supermarket with my grandparents a while ago getting a sippy for my son and it turned into a 5 min debate whether to get the orange Cars sippy or the Yellow. My grandmother asked, "Is this a big decision?" To me it is. It's not just a cup, it's one more thing that will always be surrounding me, and I actually do care what it looks like. That's why I appreciate the looks of these bottles by Adiri. They actually look like someone spent some time thinking about what they look like. On top of that it looks like they paid just as close attention to how they work. Making it BPA free and selling them for $10 each just seals the deal for me. Now if only I had another baby....
