Potty Humor

We have been teaching some basic sign language to the kids - this is something we started when Georgia was 6 months, once she learned to really talk we kind of stopped and now that Owen is past 6 months and eating foods, we have started again and it is all coming back to Georgia very well. She knows the signs for please, sorry, eat, milk, more, all done, mommy, daddy, help, and poo - she also made up signs for Georgia, Owen and Pee. Owen hasn't started to use any yet.
Georgia sometimes will randomly throw a "sign" into a conversation
Today while we were out for a drive she started screaming POO and then we would hear Owen laugh, I looked back and she was doing the "sign" for poo every time. She also started screaming pee and doing her made up sign, rotating between the 2 words/"signs".
With every word out of her mouth Owen laughed hysterically. He has a sense of humor - potty humor!
My 2 year old and 8 month old are already laughing at and making Potty Jokes - and even signing them!
I'm so proud!
