A group of scientists have figured out why we need sleep and why it's so important for babies!
The found Sleep helps build the brain’s infrastructure until the age of about 2-and-a-half. After that, it takes on a sort of de-cluttering role - brain maintenance and repair in place of brain-building
The brain grows "very rapidly" in the first two years of life, and during REM sleep a young brain is busy building and strengthening itself – so, really, do not wake up a sleeping babies important work is being done in their brains - basically sleep is just as important as food
