pampers swaddlers when they are newborn, huggies newborns leak SO SO SO bad. and, then once they're in a size 1 diaper i switched to huggies. they dont leak, and thats what costco sells, so i just get a huge box and it lasts me almost 3 months.
as for wipes, i use either huggies or the costco brand. mostly costco brand. they're thin and you have to use more than the name brand ones, but they're cheap and convenient.
