You want to be a girl again! Of course! But this sentence won't work "boy" and "his" can't both be changed. You refresh the sentence hoping for something more helpful.
"The toddler pees in his potty."
Wow you didn't even realize that was happening. In either case now you have a sentence you can change. As you go to edit "his" you are startled by your mother clapping and swipe your finger across the screen. You look down to see what you did.
"The toddler pees in his diaper."
You find yourself now lying down in your bed and feel the wet diaper around your waste. You hear your mother talking in the hall.
"You know boys develop slower than girls. He'll potty train when he's ready mom."
You can see the woman she's talking to peek into the room and are surprised to see it's your actual mother. It looks like your new mother took your old place, weird. In any case you should probably get back to fixing yourself.
