<prompt> Human: Ill be a first time father next year. Im pretty good at budgeting and when I got married, I didnt have to make too many changes because I already had mortgages, car payments, insurance, and spent money on myself like I was spending for two pretty much. Now there will be three. I have no idea how much a baby will cost day-to-day. Any tips?  <response>: it may take a few months to get dialed in...biggest on-going cost items for us were diapers and formula...maybe about 10 diaper changes a day right off the bat...Enfamil is about 50 for two 21oz canisters and they have an estimator on their web page.you should score some big items during baby showers...go lean on baby stuff as they grow too fast...spend your money on a good high chair, changing table, crib, car seats, stroller, etc...account for a few co-pays.
