●Our diapers are $45-50/mth, Wipes $20-32/mth & Formula $86/mth (breastfed until mth3 due to 2 surgeries in our first 7mths after Csection- nursing was personally just as expensive for us with a few nursing tops, extra parts, Hakaa, extra bras & washable pads, sterilz/cleaning everything, bags, extra nutrition). So I would personally sock away at least $150-170x12mths for a ballpark 1st year. [2nd year just account for diapers & wipes, groceries & preschool ($$) if you start at 2-3] Then there's the $20-30 here & there at different developmental stages for random things people don't gift- new socks every 4mths, switching up nipples on bottles, bandana bibs for drool & wipables eating, dishes/spoons/teethers, infant tylenol/teething tabs/motrin, aquaphor & nipple cream you run out of, switching up to convertible carseat, muslin canopies for summer/heavy winter, shopping cart seat cover, the occasional new developmental stage toy as they progress. Oh! And def register for extra quilted sheets & a Nose Freida/bulb syringes & spray saline for winter
