Get into the playpen.

You put the present down on a table piled with other gifts. And open the gate to step into the playpen. As you do, you realise you are dressed in a romper, styled like a sailor suit. The bulge of your own extremely-thick diaper is obvious underneath.

"Wait." you say, trying to step out of the playpen. "I'm not a baby." However, the gate is already shut and you can't seem to open it.

Tanya sees you struggling with it. "I think somebody needs his paci." She sticks a blue pacifier into your mouth. You find it is actually comforting and you begin to suck on it.

"Oh dear." A woman says. "Someone's done poopies."

You worry for a moment that it might be you but you turn to see the woman has lifted Sarah's skirt and is pulling out the back of her diaper to look inside.

You watch as Tanya takes Sarah out of the playpen, lays her on a plastic mat and untapes her diaper. As she wipes Sarah clean you realise that you need to pee. Without thinking, you release your bladder into the diaper.

You wake up and very quickly realise you didn't just pee in your dream. You've wet the bed.

You strip the bed and shower, leaving your mattress uncovered and your window open in the hope it will dry out before tonight.

You wonder if maybe you actually should buy some diapers. Just in case it happens again.
