HOW LONG SHOULD A NAP BE?
Do not limit the length of your toddler’s day sleep if he sleeps well at night. At around three years of age, your toddler may start waking in the middle of the night and not wanting to resettle for up to an hour. This may be an indication that your toddler is having too long a day sleep. In this case limit the day sleep to one to one-and-a-half hours and then wake your little one.
