Parents of three, Jason and Tiffany Mertlich, decided to reveal the sex of their unborn child by baking a cake and having their three children find out once they see the color of the cake's inside.

It all goes well and the children are excited, until the eldest and only son Gunner lifted the slice of cake only to see a pink sponge. Let's just say he didn't take it well.

His sisters Paisley and Harper seemed excited, but Gunner cried, a lot.

‘It’s a girl!’ he screamed through the tears. ‘It’s another girl! I hate girls! Every time it’s girl, girl, girl, girl!

‘I want to leave this house and never come back. I want to be by myself.

'It's too much girls!'
