Perfect for babies aged 1 months, this slow flow 120ml bottle provides calm and comfortable feeds. The Natural Response teat supports baby's unique suck, swallow and breathe rhythm, only releasing milk when baby actively drinks, making it easy to combine breast and bottle feeding. Made of pharmaceutical grade borosilicate glass, this glass feeding bottle is heat and thermal shock resistant. It can therefore be safely stored in the fridge, warmed, and is also suitable for sterilisation.
