Hand washing: how the skill grows from 15 to 36 months

Hand washing means washing hands with water and soap, rubbing, rinsing and drying. It is a short daily routine that toddlers can take over one step at a time, starting with holding their hands out.

When hand washing usually shows up

Holding hands out for you to wash them is a CDC 18-month milestone. Doing more of the routine, with help for the soap pump, the tap and the backs of the hands, usually builds over the third year.

This page follows hand washing from 15 to 36 months, a window that spans the 15-month, 18-month, 24-month, 30-month and 36-month CDC checklists.

In the library, 5 activities practise hand washing (4 as their main skill), for ages 16 to 36 months. One of them needs no prep and takes 10 minutes or less. By age, they sit closest to steps 2, 3 and 4 of the 5-step ladder, most (3) on “Does part of it”.

Related items appear on the CDC checklists for 18 months.

Skills practised alongside

The activities for hand washing most often also work on following two-step directions (1), helping with dressing (1), imitating actions (1), pointing to pictures (1) and potty awareness (1). Pairing them keeps practice playful: one activity, several skills.

Practise it inside everyday routines

  • Wash hands at the same moments every day: before meals, after diaper changes or the toilet, after outdoor play.
  • Sing one short rubbing song so your child knows how long to keep going.
  • Set up a stable step stool and a towel hung at child height.

What to avoid

  • Hot water from the tap; test the temperature on your wrist and keep the hot tap out of reach.

When to mention it to the pediatrician

Hand washing is a learned routine rather than a skill to test. If by 18 months your child will not hold their hands out to be washed, or reacts with strong distress to water and touch every time, mention it to the pediatrician.

Worried about hand washing between visits? Call the pediatrician; CDC's free resources also explain how to contact your local Early Intervention program directly. Milestones are for monitoring, not diagnosis.
