A Washington mother shared some joyous news with her oldest son, but he was not exactly pleased to learn that he was going to have another sibling!

Shanee Gibson Hart, of Fort Lewis, posted the video on her Facebook page and it has been shared more than 300,000 times in a week.

“What were you thinking? Why you have to just get another baby? You just have two!” Tre argued, with his adorable little sister taking it all in next to him.

And then he throws out a word that you don't usually hear from a 6-year-old:

"This is exasperating!”
