I think i am about to give up bf
My other 2 dcs were ff after failing to bf
I used to put cool boiled water into a bottle then add the powder when they wanted a feed.
My sister who has just had her 4th dc has always ff and makes up their bottles the same way i did, nobody has told her the new guide lines.
I know it tells you on the tin how to make up bottles but once you know how to make something you dont read the instuctions iykwim.
