Infant daycare in Seattle, WA

Infant rooms are the most staff-intensive care in any building: in a licensed Washington center, one caregiver may be responsible for at most four infants, in a group of no more than eight (some programs staff 1:3 with a group of nine). That is the strictest ratio of any age band — and the main reason infant care costs the most and fills first.

The 2024 median price at licensed King County centers was $2,530/month for full-time infant care; the handful of Seattle providers that publish infant rates list roughly $3,200–$3,800. See the cost guide for what drives that number, and paying for care for subsidy and FSA help.

Seats are scarce — 102 of Seattle's 341 licensed programs take babies under 12 months, and infant waitlists run the longest. Many Seattle parents join lists during pregnancy; the waitlist guide covers when and how.

On an infant-room tour, beyond the standard ten questions, look for:

• Safe sleep, visibly practiced — babies on their backs in bare cribs, one per crib. Ask to see the nap room mid-nap.
• Primary caregiving — the same one or two adults handle your baby's feeds and diapers, and they've been on staff a while.
• Babies out of containers — held, on floor mats, doing tummy time; not parked in swings and bouncers.
• Same-day communication — feeds, naps and diapers reported daily, by app or paper.
• A realistic sick policy — clear exclusion rules beat vague reassurance in a room of pre-vaccine-age children.
