Hegen’s 330ml/11oz Feeding Bottle is suitable from the sixth month and it comes with a Fast Flow Teat that meets the need for a fast milk flow rate during weaning. This larger size is also suitable for converting into a drinking bottle for when baby grows older, simply by changing the teat and collar to a drinking spout! Additional teats of various sizes (all sold separately) allow mothers to simply swap to their choice of teats for baby’s perfect feed as time goes by.
