We love our new #OSipLids! This is a game changer for those will little ones. It makes meal time less stressful- no spills, and no leaks! Little Man thinks they are awesome because they come in fun colors and he can use big kid cups easily with them. They are small and easy to toss in your bag for those locations that don't have kids cups (and you know a take out lid on a glass just doesn't hold up!) They are made out of a food grade silicone, are dishwasher safe, and they are only one piece (so no missing valves, or mismatched parts, and no hiding spots for yucky germs/mold).
As seen in the picture below, the bottom folds up inside to make it smaller; and they are easy to store (or bring with you) since they are stack-able for space saving at home!
They also make a version that isn't a sippy cup lid, it has a hole for a straw and works the same way.
