A new mother gorilla was trying to take a break from her one-year-old son.
The park staff had given her a special place to rest away from the other gorillas, but security cameras captured a very strange moment.
The mother picked up her son and threw him over a low metal barrier, then walked away to rest.
Her son climbed over the barrier and started trying to reach his mother again.
As soon as the mother saw him, she put both hands to her head in disgust.
When the rangers saw the scene, they provided the son with new toys to keep him occupied so the mother could rest in peace.
