Embarrassing moment

To start this blog off right, I am not even sure I spelled embarrassing right - adding to it all!
Zion has been doing pretty good with the potty training. He usually only has one accident a day in which he pees his pants. But, I have been cleaning poopoo out of abnormal places a lot lately. Sometimes his underwear, more often the floor. First I will tell you the funny story. Last weekend Andy's parents came down to visit. We put the boys to bed, and heard someone moving around, but just ignored it. Zion has gotten much better at going to bed, but still fights it, so we just assumed he was getting a new stuffed animal to sleep with, or getting a book. When it got quiet Andy went to check on him. He came back just laughing his head off. Zion was laying on the floor, sound asleep, buck naked. I went to go see it, and try to wrestle some pajama's on him so he would be warm. The reason he was buck naked was because he had pooped in his diaper, then taken it off, laid it neatly beside him, then proceeded to go to sleep. Maybe you had to be there, but it was really funny.
This week he has been doing much better. He had actually gone in the toilet a couple of times, and I was so proud. But yesterday we went to a new friends house. First time we were actually meeting in person. So I show up, and the kids are playing nicely, then I hear Zion crying. He had diarhia (sp?) running down his leg, all over his shoe, and onto the rug. First time I have met this person (we met through a homeschool online forum), and my kid poops all over her floor, and himself. I was horrified. Wanted to melt into the floor and die, beyond embarrassed. Poor Zion is just standing there, sobbing. Poor kid. He ended up having diarhia about three more times that afternoon, so he obviously had an upset stomach. I kept a diaper on him for the rest of the day.
Darlene, my new friend, proved herself as a real friend. She was fabulous, even finding a pair of her daughter's shoes for Zion. (he got to wear pink Dora shoes for the afternoon, and didn't mind one bit). I guess it could have been worse, but it was plenty bad enough for me. I am emotionally exhausted just by retelling it!
Zion is back in underwear today, and has already peed his pants once. I am afraid that wearing a diaper all day yesterday made him forget that he has to actually go to the toilet to pee. We'll just wait and see if he is reminded easily, or if we are going to have to start over again!
Since I am completely blaming the Domino's pizza for his upset stomach, we will avoid greasy nasty food for awhile, and hope that he is all better. I am going to my grandparent's in FL this weekend, so he better be well!!!!!
I have five kids today, so need to stay on my toes and focused. Thanks for listening, and I'll try to write again, and post pictures from our trip to FL.
