WATCH: Kids’ Reaction When They Find New Adopted Brother Under Christmas Tree

This is just beautiful.

A Texas mum gave her children an unmatchable surprise this Christmas – a new baby brother.

According to Cosmopolitan, when Courtney Solstad’s adopted son Nathan came into her life, her other children didn’t know anything about him.

She decided to introduce him in an extra special way, by telling the girls that there was a surprise under the tree for them.

She wrote:

The girls knew nothing about Nathan until this. We met them at the door and told them that we had been out Christmas shopping and got them a gift to share…and it was under the tree!​

Their reaction is just amazing. They completely lose it.
