I'm so over the Playtex insulated ones. We have bought no less than probably 8 of these cups, and after a few days or a week, they all start to leak. They leak out of the straw when they're turned over on the floor (or in your purse, grrr), and sometimes the liquid even comes out when it's sitting upright from the pressure inside the cup. I'm so over them.
What do you use? I need something that doesn't leak when it's been thrown on the floor and sits there awhile, as that's what tends to happen to ours. :-)
Re: What's your favorite straw cup for toddlers?
This is my favorite too.
