Where the numbers come from

The National Sleep Foundation convened an 18-member panel in 2015 that reviewed the published studies on sleep and health outcomes for each age group and voted on three bands: recommended, may be appropriate for some individuals, and not recommended. For toddlers (1-2 years) the recommended band is 11–14 hours per 24 hours; 9–10 and 15–16 hours may be appropriate for some, and under 9 or over 16 is not recommended.

A second panel, convened by the American Academy of Sleep Medicine in 2016 for children and teenagers, reached 11–14 hours for this group (naps included). The two panels disagree by at most an hour at the edges, which is a good sign the ranges are not arbitrary.

The recommended band for toddlers spans 3 hours, which is one of the wider bands — individual need varies most at this age. Compared with infants (12–15 h), the toddler range is 1 hour lower at the bottom and 1 at the top. The next group up, preschoolers (3-5 years), moves to 10–13 hours.

What too little looks like for toddlers

For toddlers, both panels note that too little sleep shows up first as behaviour — attention, mood and learning — before anything else. The ranges include daytime naps, which is why the numbers look large next to adult figures, and both panels stress that a child's needs change month to month.
