Boon Fluid Sippy Cups

I honestly have mixed feelings about these. They're awesomely weird. I bought these before my baby was born, because of the way they looked. they somewhat remind me of the baby bottles from the 80's. They have awesome colors, you can mix n match the lids, they just snap on, which causes a con for this cup.
My daughter got mad the other day, and threw it to the ground, and the lid busted off, spilling the entire drink everywhere! Luckily, we were in the kitchen. It also fits perfect on my maclaren volo stroller! But other than that I think they are for older toddlers like 2 and 3 year olds. Boon is great, I highly recommend them. They have new released cups, I can't wait to get! I do not recommend the swig. Horrible! My daughter lost it in Disney world, it's not missed. I'm all for trying new cups. Right now, my daughter is liking the Gerber graduates. My other 2 did as well. Gerber always ends up on top.
