Has anyone done it successfully? My neighbour is trying to bf and her hv said it was ok to introduce 1 ff at night and I think she sometimes does 2. I know a colleague who went down this route and her baby fully ff very quickly but I wondered if anyone has managed it. She is also feeding lots and lots in the day which is very usual in my experience but I wonder will it make up for the bottle/s? I did tell her about supply issues but she didn't take it on board.
