Inchbug.com; 4 for $12.95Everywhere I take my daughter, I take a sippy cup, a snack bowl, or some other plastic (BPA-free!) container. I'd say about 50% of the time they make it home with me.
I feel like I'm constantly buying new ones because I can never find one when I need it. They've all likely been left at the gym day care, school, playgroup, or a friend's house. No one knows whose is whose because all the "permanent" ink with each child's name has long since washed off.
That's why I was thrilled when I found BumpyName Orbit Labels -- they're the kind of brilliant, I-should-have-thought-of-that product that actually makes life easier for moms.
They're basically big rubber bands that you can slip around all sorts of containers like bottles and sippy cups. You can have them personalized with your child's name, allergy information, phone number, or anything else.
You can reuse them over and over again, and they're dishwasher-safe. The price isn't bad (4 for $12.95) either, especially compared to buying a new sippy cup every other day. And they're super-cute to boot.
Basically, you need them!
