Who said you have to throw your bottles away when your baby is done with nipples?! Now you can easily convert your Chiller's inner chamber or any narrow-neck bottle to a sippy cup with our beautiful sip-top lid! Also fits the Ceres Chill Cup with the connector!  

This special, patented sippy cup attachment is convenient and easy to use, so you can keep your little one fed or hydrated wherever you're headed.

• Convert any narrow-neck bottle into a sippy cup by swapping out the nipple with the sip top lid to allow your growing baby to gradually develop from infant nipples to toddler sippy cups.
• Made out of 100% soft and durable silicone that is gentle on teeth and gums. 
• Comes as a set of two (2) so you always have one when you need it.
• Easy to clean — just toss it in the top rack of the dishwasher!
• Read the complete product guide for how-to instructions.
• Comes with a Lifetime Warranty.
