How much sleep does a baby need?
Babies, 4 to 12 months need
12 to 16 hours a day, including naps
A range, from a consensus statement
Counting naps. Sleep at this age is still spread across the day and the total is what matters, not the shape of it.
What the recommendation is and is not
The figure comes from the American Academy of Sleep Medicine's pediatric consensus statement, which was arrived at by a panel reviewing the published evidence on sleep duration and health outcomes rather than by measuring what children actually sleep. It is a range within which outcomes are good, not a prescription, and a child consistently at either end of it is not doing anything wrong.
