Dr. Brown's Natural Flow® Options+TM 広口ガラス哺乳瓶用シリコンカバー

The silicone is so much grippier than the bare glass, and it actually makes the bottle easier for my little one to hold during feedings. I love that it’s removable too, so I can wash it separately when milk gets in the nooks.

These sleeves are a lifesaver for my clumsy baby, the silicone is grippy enough that the bottle barely slides even with wet hands. They pop on and off easily for a quick rinse when he decides to chew on them mid-feed.

My little one kept dropping the bottle and I was terrified of glass shattering, but this sleeve is grippy enough that I feel way more at ease. Being able to take it off and just toss it in the dishwasher is a total win for me.
