HOW lovely is this video?!
A proud grandmother put the film on YouTube, describing it as "My 6-month-old grandson Preston Little and 2-year-old chimp Mabusu interacting at the Sedgwick County Zoo in Wichita."
The baby and the chimp are obviously having great fun monkeying around, as they ape each other's movements through the glass.
Gorgeous baby Preston can be heard giggling in delight as his hairy playmate tries to touch his fingers and toes through the window, at one point even appearing to plant a kiss on his little tootsies!
Watch it for some cute overload.
