Look a lot of "needs" aren't
You can cosleep or atleast have the baby in your room saving you from the crazy cost of setting up a nursery, buying a crib etc
Breastfeed, esp if you have a baby with allergies who would need special formula, cost of pump and bottles $300-450, formula for a year $1000-1300.
Clothing can be bought cheap, lord knows you can always find the small sizes at end of season sales.
Diapers, $30-40 a month disposables, or try cloth
bumGenius cloth diapers by Cotton Babies that's a diaper than will take a baby from 7-35 pounds, investment of $400 for the whole diapering life of the baby.
Medical, check now and see how much your insurace will cover and find out a general idea of cost, I had a vaginal birth, but dd wasn't breathing and even tho the midwife got her started I ended up paying $700 + for 5 mins of a ped cardiologist who listened to her heart once and gave me nasty looks
and I got nickled and dimed by the hospital, always ask for a detailed bill!!
It would have been cheaper for me to have a midwife home birth and pay out of pocket.
Now child care is where the $$$ comes in, some areas it's cheaper to be a sahm because childcare is no nuts, I'd call around and price it out that in your area.
Anyway to answer your question now at age 2, I spend roughly 1100-2000 a year on dd for EVERYTHING inc gifts, she has allergies but has only needed one visit outside of her normal well baby visit.
