Upper end of 5 figures is somewhere more than $50,000. Unless you went to an out of network hospital, and the kid ended up in the NICU, I doubt the total would be that high.
i also exclusively pumped for a year, which cost a few thousand dollars. the pumps alone were $1200. then replacement parts, accessories, random necessities.. can't even count the time and the calorie investment involved (i was eating upwards of 1000 extra calories a day to prevent weight loss).
throw in gear and clothing and...going past $50k for the first 18 months doesn't seem so unrealistic?
Also, one pump is required to be provided by the health insurance company by law, and as now, a new pump costs a a few hundred dollars. This is the most popular one:

A crib/car seat/rocking chair/stroller can be had for $1k total if you stick to mid level stuff, maybe a few thousand if you go super fancy. Food and clothes might be another few thousand.
I wouldn’t count one’s time cost to be of importance to the conversation either, as it’s universal. If we’re comparing how much money came out of parents’ pockets with a baby versus not having baby, I would say at most $10k for most people, I would budget for $15k though (and lost wages due to time off if you don’t have paid parental leave).
based on your math and assumptions i really wonder if you have had a child in the US recently.
