Why Infant Care Costs More in St. Louis
Infant care in St. Louis costs more than toddler or preschool care for two reasons:
- Staff-to-child ratios: Missouri requires roughly 1 caregiver per 3–4 infants vs. 1 per 5–6 toddlers and 1 per 8–10 preschoolers. More staff = higher cost per slot.
- Specialized care: Infants require feedings, diaper changes every 2 hours, and individualized sleep schedules. That labor intensity keeps wages and staffing costs high.
The cost premium for infant vs. toddler care at a St. Louis daycare center is approximately $1,500/year. Once your child turns 18–24 months, costs typically drop 12%.
