Toddler Napping Twice a Day
Many toddlers continue to take two naps a day, although most have made the switch to one nap by that age. There is no reason to be concerned if your child continues to stick with his morning and afternoon nap. By 22 months, he will likely make the switch. There is also no reason to rush this transition, especially if he sleeps well during the day and at night.
One sign that your little one is ready to make the switch is that he sometimes takes a long time to fall asleep or doesn't sleep at all for one of his naps. Another sign is that he does fine on days when he happens to miss one of his naps. Once he is ready to make the transition, expect it to take up to a few weeks for his body to totally adapt to one nap, and know that he may still have some days where he'll need both naps.
