Thats the thing isn't it - we jam pack our lives, our society is fast, rushed and busy and that means we need every ounce of sleep we can get to catch up with ourselves - then introduce a baby! But these little beings dont carry our burdens or pace of life yet, so they need less sleep to recharge their batteries which is a problem for us mummies and daddies! We need it because we are absolutely buggered, but babies are different.
