Let them sleep on it! Here's some more incentive for getting your lil one down for a nap. A new study by researchers at the University of Arizona in Tucson has found that infants learn better when they nap within four hours of learning new information.

According to the findings, tots who received daytime naps soon after learning a new lesson exhibited abstraction, an advanced level of learning where the brain detects patterns of new information. While both children who did and didn't nap recognized the new data they were taught, those who napped demonstrated a better understanding of the lesson than those who did not. The researchers emphasize that it is still important to provide babies with high levels of stimulation through reading and talking, but it should be paired with regular daytime naps to increase wee ones' levels of retention.
