If you have a child that uses a Tommee Tippee sippy cup, you will want to check out this list and see if you have a cup with a problem.

I will give the company credit. At least they're doing this recall voluntarily instead of being forced to by the FDA. Tommee Tippee is recalling 6 different sippy cups. Here's the reason they stated on their website.

Mold can develop on the removable, one-piece, white valve inside the cup when it remains wet/moist and is infrequently cleaned.

Although the resulting risk of gastrointestinal symptoms and infections in consumers with compromised immune systems is low, the product is being voluntarily recalled in the US and Canada.

What models of sippy cup are affected? Here's how you can tell according to Tommee Tippee.

Tommee Tippee Sippy Cups with a removable, one-piece white valve (shown below), sold between December 2014 and March 2016 in the USA and Canada. Tommee Tippee Sippy Cups with a different valve are not affected.

What to do if you find out you have an affected cup? First, definitely check out the official website for details. Then, you can fill out this form to take care of getting a replacement.
