well lets see if you go to costco(or bj's in other areas) and buy a big back of diapers that last usaully about 2 weeks and is about $34, a can of formula is about $13- $14 dollars and if i can remember correctly i went through about 4-5 cans a week.you should have the clothes before hand weather you buy them or get them from your babyshower, so really all you need to worry about for the first couple of months is diapers and formula. how old are you? you could also get things like w.i.c which helped me out alot, my son is going to be 4 next week and i too am 8 weeks pregnant;) good luck
