Our children were born 2 years apart. Our son was our first arrival and fortunately was potty broke before our daughter arrived. However, as our daughter began to grow and follow her brother as they all do, things were always a comical situation as the daughter tried to mimmick big brother.
My fondest memory was when we were potty breaking Abby. She was around 2 years of age, and big brother was around 4.
I peeked into the bathroom one day to see what the little tykes were up to, and couldnt believe my eyes. Big brother had his pants down to his knees, and was urinating in the big boy potty as he was taught to do. And what was little Abby doing, you may ask?
She was standing there beside him, her training pants also at her knees, and had actually turned her belly button wrong side out and pointing it at the toilet!!
I had to turn away at that point..I was laughing so hard I couldn't breathe.
