Melanie Darnell is famous on Instagram as “fitmomma4three”. She uses her account to share fitness videos and healthy recipes, to motivate other mothers and families, and to document her seemingly perfect family life. But with her husband out of town for work, and three restless children in the house, she decided to find out just how much sleep she was getting through the night.

She duct-taped a camera to the ceiling in her bedroom in order to find out. The video above, titled Why Moms Wake Up Tired, shows Darnell tossing and turning through the night, woken up on several occasions by her restless children, whom she cuddled and comforted.

“Parenting doesn’t end when the sun goes down,” she wrote in an Instagram post (below). “The 4am wake-up call is especially excruciating. Still, we haul ourselves out of bed, and with bleary eyes pull our babies in close.”
