how do I extend my 10 month baby's lunch time nap? he is sleeping only 1 hour

A. hi dear Experts note that babies this age sleep for a total of about 12 to 16 hours per day. This breaks down to roughly 9 to 12 hours of sleep at night, as well as a total of 2 to 4 hours of naps throughout the day — usually spaced out as a late morning and mid-afternoon nap.
