Feeding Bottle Handle Grip for Comotomo Feeding Bottles (Set of 2, Green) Our bottle handle grips are compatible with both 5 oz and 8 oz Comotomo bottles. Uniquely designed to not only prevent slippage, but to support the babys grip, which is especially important at the early stages of self-feeding. Strong and flexible, yet soft enough for tiny hands. Fill and close the bottle. Pull the handles up from the bottom of the bottle. Stop when the top of the handle touches the bottom of the nipple ring. Take the open bottle and place the handles form the top. Fill the bottle. Firmly tighten ring/nipple onto bottle. Pull up and straighten the handles as necessary for best fit.
