It's a good thing I got back from Las Vegas when I did; turns out there are too many wet pairs of underpants around the house for one parent to handle easily by herself.
The kid's in a state we might call aggressive regression. For the last few days, she has been having accidents several times a day--including on most any lap she sits down on--and has reacted poorly to having to change her underpants and clothes so often as a result.
But even when I think my question about changing clothes sounds nonchalant--usually asked right after I see her pee on the floor or right after she climbs off my lap and I see a big wet spot on my thigh--she gets really agitated. She even denies that she had an accident. [I feel like saying, "Kid, if it were farts and there were more than two people here, that line might work; but you just peed on my leg." But I don't.]
It's like we're taking two steps forward and two steps back with the toilet training. And frankly, we're stumped.
