How many hours did 10 months old baby sleep

A. At 10 months old we'll aim for at least 13.5 hours of total sleep per day (11-12 hours at night and 2-3 hours of day sleep over 2 naps). Most children need 3-3.75 hours of awake time in between sleep periods at this age. [Note: for children who were born early, we go by their adjusted age for sleep development.]
