In the big book of cuteness guidelines, (if there are  in cuteness guidelines) then a sleepy happy baby would check off three boxes. Sleepy, check. Happy, check. Baby, check. This little girl can’t seem to stay awake… but when she is, she’s deliriously happy and charming. This is only cute when you’re a baby. If you’re sixteen years old and behind the wheel of a car when this happens, the cuteness factor drops off dramatically.
