Why is sleep so important for little ones? Because it is their brain food.
Consolidated, restorative sleep is imperative for proper brain growth and development. This becomes especially important after the age of 4 months when a cognitive shift happens, influencing the structure of sleep cycles and restorative properties of sleep.
Sleep provides brain food in the way of processing sensory information and stimulating cellular growth. A child who can self-soothe, one who can independently transition between sleep cycles, will receive the most restorative and cognitively productive sleep possible.
