Check out this heartwarming video of a big brother rocking his toddler young sister to sleep. She looks like she is sleeping better than on a million dollar mattress, the obvious giveaway is the thumb in the mouth.
But it is somewhat hard to say who is enjoying this little nap time more, the big brother, who is around five, six years old, or his baby sister that is still in her diapers.
As some users on Reddit have confirmed, and in case you are wondering, the little girl has achondroplasia, which is a genetic disorder that results in dwarfism.
