1 Year +: What This Month Costs, What to Buy, What to SkipModel month ~$150/mo model · about 6 diaper changes a day · Milk transition per pediatrician; food is groceries now. All prices are model examples — run your real numbers in the simulator.
Past the first birthday the baby bill changes species: diapers continue (toddlers are not done — budget roughly two more years of them, falling slowly), formula usually transitions to milk and food on your pediatrician's guidance, and childcare — if it enters your life — becomes the line that dwarfs everything on this site combined.
Model month at 1 Year +
■ Diapers — $43 ■ Feeding (formula model) — varies by family ■ Wipes & basics — $39
Feeding is shown at a formula-model level for scale; breastfed and combo-fed months sit lower on that segment only. Everything else is stubbornly similar — babies are egalitarian that way.

Redirect the freed formula budget deliberately (savings, debt, help) before it evaporates into lifestyle drift.
Start the potty-readiness watch without buying the gear yet — signs first, purchases second.
