Understanding Toddler Sleep

Toddler sleep can be challenging as children this age are developing independence, experiencing separation anxiety, and transitioning through major developmental leaps. Understanding your toddler's sleep needs and maintaining consistency are key to healthy sleep habits.

Most toddlers need 11-14 hours of sleep in 24 hours. This includes nighttime sleep and naps. The transition from two naps to one typically happens between 15-18 months, and most children drop their last nap between ages 3-5.

Common Sleep Regressions

12 Month Regression

Standing in crib, separation anxiety, and nap transition can disrupt sleep. Stay consistent with routines.

18 Month Regression

Peak separation anxiety and newfound independence. Offer choices within boundaries and extra comfort.

24 Month Regression

Language explosion, potty training, and big kid bed transitions. Address fears with understanding.

3 Year Regression

Imagination development brings nightmares. Dropping nap can cause overtiredness. Implement quiet time.
