At what age did you move up to medium flow nipples? DS will be four months next week, and is still using slow flow. We have tried a few times to move to the medium but they are still too fast for him, but he takes forever to eat with the slow flow ones because he's eating 8 oz. I thought by 3 months he'd be on the mediums!
Did your DC transition easily to mediums or did it take some getting used to? I don't know if I should back off and leave it be or try to get him used to the faster flow?
