Hello, my son is almost 6 weeks old and we are going to introduce a bottle to him for one feeding a day until he goes into childcare at 12 weeks old. At that point id like him to continue breast feeding at home and take a bottle during the day while I am working. I want to exclusively breast feed as long as possible and am looking for a bottle that will not create nipple confusion, has a slow flow, and is a “nipple-like” as possible. Suggestions? Nuk Simply Natural? Comotommo? Thank you!
