when do babies drop to one nap

Babies typically drop to one nap between 12 and 18 months of age, with many transitioning around 14 to 15 months. This transition involves gradually dropping the morning or afternoon nap to consolidate sleep into one longer midday nap. Signs that a baby is ready to drop to one nap include consistent resistance to one of the naps, shorter naps, needing a later bedtime to fit in two naps, or staying energetic and happy when missing a nap. The transition often takes a few weeks and depends on the readiness of the child. Babies younger than 12 months are generally not ready for this transition, and pushing it too early may cause sleep difficulties.
