Cost by Child's Age
Childcare prices in Sonoma County track a child's age closely, because state licensing rules require more staff per child for the youngest age bands. Infant center care costs $243/wk ($12,647/yr), the highest band in most counties, while preschool care runs $204/wk ($10,610/yr). That's a 16% drop — about $39/wk, or $2,037 a year, in savings as your child moves from infant to preschool.
The priciest age group in Sonoma County is Infant (0-1) at $243/wk, and the cheapest is toddler (1-2) at $200/wk — a spread of $43/wk between the most and least expensive bands. The decline is uneven here: toddler care sits close to or above infant care, so the cost curve is not perfectly smooth. School-age care (ages 6+) is usually the most economical at $213/wk, since those children only need before- and after-school coverage.
