11 Month Old Sleep Schedule

Eleven-month-olds are experiencing a burst of cognitive development sometimes called the twelve-month leap, which actually begins around eleven months for many babies. This cognitive advancement includes understanding cause and effect at a deeper level, developing memory for sequences, and beginning to use objects as tools. These complex cognitive processes require substantial sleep for consolidation. Research from the University of Arizona found that sleep-dependent memory consolidation improves dramatically between 9 and 12 months, meaning that quality sleep directly supports your baby's ability to retain and build upon new learning. Motor development at eleven months is particularly sleep-intensive. The transition from cruising to independent walking requires the most complex motor coordination your baby has attempted, involving balance, weight shifting, proprioception, and the integration of visual and vestibular input. Many babies practice walking movements during REM sleep, which you might observe as leg movements or repositioning during the night. Sleep efficiency at this age is typically high, with most babies spending 85 to 95 percent of their time in bed actually asleep.

The eleven-month schedule extends wake windows slightly compared to ten months, with the first window around 3 to 3.25 hours and the last window before bed stretching to 3.5 to 3.75 hours. Naps should total 2 to 2.5 hours across the day. If the morning nap consistently runs long (over 1.5 hours), consider capping it to protect the afternoon nap. A well-timed afternoon nap ending by 3:30 to 4:00 PM sets up an appropriate 7:00 PM bedtime.

As your baby approaches their first birthday, begin thinking about the transition from bottle to cup if you have not already started. The AAP recommends weaning from bottles by 12 to 18 months. You can begin by offering milk in a sippy cup or straw cup at meals while keeping the bedtime bottle temporarily. Eventually, the bedtime bottle should transition to a cup as part of the routine, ideally before teeth are brushed. Speaking of teeth, continue brushing your baby's teeth twice daily with a smear of fluoride toothpaste as recommended by the AAP. Dental health impacts sleep quality, and untreated cavities can cause significant pain that disrupts sleep. If your baby has a strong preference for a specific comfort object or lovey, ensure it is part of every sleep situation to maintain consistency. This is also a good time to begin teaching your baby simple sign language for sleep-related concepts like milk, more, all done, and sleep. This reduces frustration and supports communication before verbal language fully develops, which can indirectly improve sleep by reducing bedtime battles.
