Another thread reminded me that I've been meaning to post about these for a while. I can't recommend these enough. They're really sturdy. They've withstood so many washings and sanitizing cycles. They're bright and loud, so there's no mixing up our food or bottles with other ones. I have the circle ones with the design for my daughter. The picture ones seem cute but I was a wee bit weirded out by those.

I've used the iron-in Label Land clothing ones, and they work really well.
