So I have have been feeding my little baby since she Was born on Sunday feeding done but my milk has come in a my boobs has grown a lot and my nipple is so stretch hence breast feeding isn't an option. I have been expressing but am worried I have storenit currently ? I expressed 4 bottle yesterday and put them in the fridge and used them throughout night and keeping ? I have been heating them up by boiling water and putting them in a bowl to get warm ? Is this okay
