Natursutten Borosilicate Glass Baby Bottles (Anti-Colic)

Important note on baby bottles

Baby bottles are frequently used with warm liquids such as breast milk or formula, and heat, fat, and acidity can affect how materials behave over time. Because of that, I’m intentional about material choice and transparency. I prefer glass or clearly disclosed safer plastics for bottles that regularly hold warm milk.

What I avoid in baby bottles

In this category, I avoid PVC and PUR, as well as BPA and BPS. I’m also mindful of contaminants such as lead, which may be present in decorative paints, inks, or coatings on bottles. I look for simple designs, minimal coloring, and clear material disclosure so I know what’s actually touching the milk.

Product description

Natursutten Borosilicate Glass Baby Bottles are made of borosilicate glass and feature a silicone sleeve and nipple with an anti-colic venting system. Borosilicate glass is a type of glass known for its durability and resistance to thermal shock, which is useful when warming bottles or transitioning between temperatures.

These bottles are made for everyday feeding and come in sizes suitable for newborns onward. The sleeves provide a little grip and protection for the glass, while the anti-colic design helps ensure smoother feeding.

What I like

I like that the primary bottle material is borosilicate glass, which is more thermally stable than standard glass and doesn’t absorb odors or residues. The sleeve provides grip without adding unnecessary materials, and the anti-colic venting design may improve feeding comfort. I also appreciate that the materials are clearly disclosed.

Things to keep in mind

Even with glass bottles, there are silicone and plastic parts involved, like nipples and collars, so regular replacement and gentle care for those components matter. I avoid putting plastic collars or caps in the dishwasher, since repeated high heat can wear on plastic over time — hand-washing those parts is an easy way to be a little gentler with them.
