Transition+ is the ideal bottle for a smooth breast-to-bottle transition. And if Baby is not or has not been breastfed, it is also for him. We explain: Thanks to its flat shape and micro-perforations that mimic the breast channels, the Transition+ nipple reproduces the flow of the feeding as in the breast, for a natural feeding rhythm. With its anti-colic valve, it is the guarantee of a good digestion for baby.
