I'm helping my friend's daughter work out a realistic £££ budget for herself and her baby after its born. She wants to bottle feed - how many cans of formula will she need per week? I know its goes up after the first 4 weeks and stays about the same for the next 5 months. Is about 2-3 cans a week right? I mean the big 900g tins - I have already priced these at about £5.20 from the local health centre. I did try to work it out from the information on the can but its measured in scoops and the tin contents are in grams...sigh.....
