While looking for some food containers that I could pack food in for Winston to take on our recent trip to Lake Powell, I came across these handy little cups on Amazon.com. They really work great. Winston can reach in and grab some crackers or cereal or whatever and it doesn't spill. Not even when he drops it. Granted, he can make a mess when he really wants to, but these help prevent inadvertent spills. They're great for in the car or on the go. Also, they wash up great.
