## Questions & Answers

**Q: How do I clean my b.box sippy cup straw?**
A: We recommend straws be thoroughly washed following each use with warm to hot (not boiling), soapy water. You

**Q: Is my b.box sippy cup dishwasher and sterilizer safe?**
A: Yes! All sippy cup parts can be placed in the dishwasher, as well as a UV sterilizer or a steam sterilizer.

**Q: How often do I need to replace the straw on my b.box sippy cup?**
A: The longevity of our straws will vary between kids; how old they are, how they drink, how often they drink, are they teething, do they chew their straw, and how the straws are cleaned. If they begin to leak, consider a replacement straw pack.

**Q: Why is my child having difficulty drinking from the b.box sippy cup?**
A: The straw on our sippy cup has a pressure valve (this is the magical piece that makes it leak-proof). Kids need to place their lips over the whole straw (rather than just the tip) and press down on the straw, to open the valve and enable liquid flow.

**Q: Why is my b.box sippy cup leaking?**
A: If the leak is between the cup and lid, check that the silicone o-ring (that’s the silicone seal that sits in the groove under the lid) is securely in place. If your sippy cup straw is leaking, it may be because your straw valve is damaged/worn out.

I bought these for my grandson. They're very sturdy and take a lot of abuse (throwing/dropping on the floor) Easy to use and leak proof. Definitely recommend.

Es muy complicado limpiar el popote de esta marca si no tienes la escobilla. Así que no hay de otra más que comprarla para tener limpio. Lo hace bien.
