Compare the Kiki Kiddo Straw and Big Mouth Silicone Sport Straw on age range, fit, and use. Find out which replacement straw suits your child's bottle and drinking style.
Quick answer
Choose the Kiki Kiddo Straw for toddlers from 6 months and older who need a dedicated straw bottle setup, and the Big Mouth Silicone Sport Straw for kids 18 months through adulthood who want a plastic-free sport top for activity and school.
Age range and intended use
The Kiki Kiddo Straw is designed for children from 6 months and up, making it a natural first straw option for toddlers transitioning from bottles. The Big Mouth Silicone Sport Straw starts at 18 months and extends to adult use, so it grows with your child and suits older kids who want a sport-style top.
If you are buying a replacement straw for a Kiki Kiddo straw bottle, the Kiddo Straw is the matching module. For a school water bottle that needs to handle active recess and sports, the Big Mouth Sport Straw is the more appropriate choice.
Material and safety
Both straws are made from medical-grade silicone and are 100% plastic-free, BPA-free, BPS-free, EA-free, PP-free, polypropylene-free, and phthalate-free. They will not leach toxins like plastic bottles and lids. This means you are not trading safety for function when choosing between them—the decision comes down to fit and age.
Because both are silicone, they are soft on gums and teeth, which is helpful for toddlers and for older kids who tend to chew on straws.
Bottle compatibility and replacement
The Kiki Kiddo Straw is a replacement straw module for the Kiki Kiddo straw bottle system. If you already own a Kiki Kiddo bottle, this is the correct replacement part. The Big Mouth Silicone Sport Straw is a sport top that fits Pura Big Mouth bottles; it is not a direct replacement for a Kiddo straw bottle. Check which bottle system you have before ordering a replacement straw.
