I was wondering when do you start your LO on a fast flow nipple. Mine is 5 weeks and has been on the bottle for the last 2 weeks. I am not in any rush to switch, but today she spent 45 mins to put down 4 oz. I was just wondering if there is a certain age at which you start one or if you judge by how much they take and how well they handle the bottle.
