I would completely fuck with her and spring the nannycam ruse.
So, H and I watched the nannycam tape from when you babysat the other night. Anything you want to tell us?
And find the duplicate pajamas, are they in the hamper? Are they even in the HOUSE?
I KNOW! I would have sleuthed this out by now. Hell, I would have sniffed around the minute I got in the door!
Seriously, where are the pukey pjs? I think that's the smoking gun in the case, you need to find em. I would be pissed, youre not overreacting. My MIL once called me an evil stepmother for not letting my SDs have gum when we were visiting her. She gave it to them and I came back to the house to find her trying to scrape it off her dining room table...and the entertainment center. I realize this is irrelevant but Ienjoyed that moment and wanted to share it.
I'm pretty sure I would have just washed the pjs without even thinking. I did a load of laundry of Sunday. It never occured to me then that this happened. As for the sheets, I'm sure he was standing in crib because that's how he rolls, and potentially just got it mostly on himself. I'm sure she did a little wipe up, though.
Just playing devils advocate: Where are the nasty sheets and pj's? Could the vomit have been accidentally left there from a previous time? Just asking, not flaming.
DAYUM
Are you sure you didn't just let the dry vomit crust on the wall before, you filthbucket?
