I was thrilled,,when I finally got A SIGN,that he needed to go out, rather than just a squat right in front of me, SO when he started to give me a sign, I knew he knew the difference, he would walk in front of my line of vision,, ( usually the TV) and spin in a circle,,, and then I knew it was TIME!!
Or when the accidents would happen he would run out of the room that he just did it in,, and I would know,,, so when I would go to check, he would follow me,but slowly with his head down,,, saying " I know, I did it, I know I was suppose to go outside, I'm sorry mom"
But, when they do KNOW to go outside,,,has to be one of the best things!
