"Show Taylor what you did!" the mum-of-three could be heard saying as they walked into the room.
The brother-sister duo then approached a little, blue potty on the floor where Hudson had gone to the toilet all by himself!

Taylor sweetly applauded her baby brother and said: "Awwww," as Christina said: "Big boy!" and they congratulated the youngster on his proud moment - which given that he is only a year-and-a-half old, is pretty impressive.
Christina is a proud mum to her three children
Christina shares her two oldest children, Taylor, and Brayden, five, with her first ex-husband, Tarek El Moussa, and her youngest with ex, Ant Anstead.
The couple broke up in September 2020 but they are still working through their divorce.
It was in November that Christina formally filed for divorce and asked for joint custody of their son.

She recently asked a court for a "default and judgement" in the split as Ant has not yet responded to her filing in the Orange County Court.
If granted, this would mean Christina could divorce Ant without him responding to the petition.
While they are no longer together, the former couple are doing everything they can to co-parent successfully.
Ant told HELLO! in an exclusive interview: "Being that we both have experience with co-parenting has certainly helped make it easy. We have found a groove that works for us both and puts Hudson first."
The British TV presenter also has two children from his former marriage and they live in the UK.
