Should have stayed home...

I've never had problems with my children in public(Not huge ones anyways). I've heard horror stories from moms who refuse to go out with more than one child. I've never understood that. I don't have behavior issues with the girls. They don't touch what they shouldn't (for the most part) and the wouldn't dream of falling out on the floor because I told them they couldn't have something. I didn't realize its not a behavior issue, its logistics. I mean what do you do with the baby when the middle child has to go to the bathroom? Or your purse? Last night was a prime example of bad planning...
We went by Lowe's after work to see Daddy before bedtime. As we left, Our Fairy was crawling into the van and pulled her dress down, breaking a strap. That should have been the clue to go home and go to walmart's after Oliver got off work. However, I didn't listen. When we got to Walmart I started filling the cart with things we needed and she says "I have to go to the bathroom." So we head over to the bathroom at layaway and I stand at the door with the cart and Our Oso while the girls go into the bathroom. A couple seconds later, I hear crying. I call for Our Princess to come hold the door open so I could see Our Oso and go in to see what's wrong with Our Fairy. She didn't make it to the stall. She had peed all over the floor and in the process of stopping it, had grabbed the hem of her dress and made sure it was nice and wet as well. Now, she has never been one to have accidents. I think this would be the 2nd since she started potty training over a year ago. She's had bed issues since her tonsilectomy, but never out in public. So I've got a cart full of groceries, a baby who is hungry and starting to wake up, a little girl who is upset because this never happens to her, and all I can think is "I should have gone straight home."
So I throw out the panties...towel dry the dress, wrap her in Our Oso's blanket and put her in the cart. I grab two more things we desperately needed and got out of there asap.
Then we got home. By this time Our Oso is screaming for dinner, the girls are filthy from the playground(not to mention they haven't eaten) and I have to go to the bathroom. So I quickly glance in the oven to see if it's empty, put it on for pizza, run and turn on the tub so the girls can bathe, use the bathroom real quick and grab the baby and start to nurse him. Then I smell it...like burnt smores. I put the baby down and ran to the kitchen. Tía had made a cake and put it in the oven. There was a plastic handled knife in the pan with it. The cake was black and the knife was goo. I turned off the oven and took out the cake. Wonderful.
Anyways, when I put the pizza in the oven I forgot that I had turned it off, so the pizza took much longer to cook than normal. After that, I fed them and put them to bed and all was calm in my world. What a rush!
