For those with kids, did your spending reduce after the baby and toddler phase?

We have 2 data points for annual spending from 2023 and 2024, but both of these years have child care costs that make up a third of our spend. I'm curious, for those who have kids, did you find that costs went down after the baby and toddler phases? I imagine child care costs go down but other costs could go up like for various extracurricular activities? Trying to figure out how much we spend for the 4% rule has been tough.
