..that the baby can switch from breast to bottlefeeding and back again?
I'm uneasy with it and I don't quite know why. I think it's because so many babies who are bottlefed aren't breastfed at all.
I can understand why they'd want to sell teats that mean the baby uses a breastfeeding-type action to get the milk, but I think to say "your baby will effortlessly switch between breast and bottlefeeding if you use this teat" is shit, misleading and wrong.
