Yes to sippy cups or sport bottles!!! I decided on a recent trip that it was time to leave them behind. We were about 1/2 hour into the 8 hour flight when my daughter knocked a full glass of apple juice onto her lap. Thankfully I was packing an extra set of clothes. You just never know what is going to happen. The journey didn't actually get better after that. To make you feel better about your own family trials and tribulations, I wrote about it here. LOL.
