Kaakaababy Glass Bottle with Silicone Straw and Sleeve

This KaakaaBaby glass baby bottle is built to grow with your child — from their very first sips as a newborn right through to confident toddler drinking. The borosilicate glass body is thermally shock-resistant and taste-neutral, so nothing leaches into milk, formula, or water. A protective LFGB-certified silicone sleeve cushions every drop, and the bottle ships with our original silicone straw with an internal anti-spill valve. As your little one grows, simply swap the topper — straw, spout, or teat — without buying a whole new bottle.

Why Parents Choose This Glass Baby Bottle

If you’re researching glass baby bottles, you’ve probably already landed on borosilicate glass and LFGB-certified silicone as the materials you want — and this bottle ticks both boxes, with nothing else between your child and their drink. It’s also one of the few glass baby bottles designed as a long-term system rather than a single-stage purchase: the same 270mL glass body works with our Topper Bundle – Grow Collection, so you can move from straw to spout to teat as your child’s needs change without replacing the bottle itself. We built it this way after years of buying a new bottle for every age and stage — it felt wasteful and added up fast, so one glass baby bottle with swappable toppers felt like the obvious fix. For families who’ve already chosen low-tox feeding gear, it’s one less thing to second-guess.
