How many do i need ? (baby stuff)?

its different for each baby, depends ho big they are at birth and how fast they grow. i have a 4 1/2 month old thats in 9 and 12 months clothes, and have a friend whose son is 7 months and only in 3-6. it all depends. as far as diapers go online and register for coupons. i was told that huggies was the best brand for boys by pretty much everyone i know, but they leaked really bad on my son. the best way to figure out which works best for your baby is to buy small bags of each brand and see which ones work. every baby is different so there is no exact answer to your question, the best thing to do is just go with the flow. good luck and congrats.
