Most toddlers stop napping between ages 3 and 5, although this can vary. About one-third have stopped by age 3, and most transition away from naps during the preschool years. By age 5, nearly all children no longer nap.
This change happens as sleep shifts from daytime to nighttime. As toddlers grow, they are able to stay awake longer and get enough total sleep overnight instead of needing naps. Some children may still nap if given the chance, especially in structured settings like daycare, but may skip naps at home.
It is normal for this transition to be gradual. A child may nap some days and not others, or take shorter naps before stopping completely. What matters most is that they still get enough total sleep in a 24-hour period and remain alert and well-rested during the day.
If your child is having trouble with sleep, frequent night waking, or daytime irritability, it can help to speak with a pediatrician. Avoid using sleep aids without medical guidance.
