big steps for a lil girl

i just have to tell this cute story.
ayu is a darling little girl. she's 2.5 years and has the chubbiest cheeks ever. she has a really expressive face and you can immediately tell if she's upset about something. she babbles all the time, but doesn't make any sense. i'm fairly good at japanese and can usually tell what the kids are saying in japanese, but i could never understand her. one day, i asked one of the japanese teachers if ayu makes any sense in japanese. and they said no. haha.
a few times a day we do diaper changing/toilet time. usually, i stay in the classroom and change diapers and my assistant takes the kids to the toilet. ayu is in the diaper changing group.
well, the past few days she has been really grumpy and sad. her mom was getting worried because she was saying that she didn't want to go to school. yesterday, the first time we changed diapers she was really pouty and told me "no!" but i still made her do it.
later in the day, my assistant also said she didn't want to change her diaper. i was brushing ayu's teeth and trying to give her some extra love because i could tell that she was sad. i was trying to get her to tell me what was wrong. as i was talking to her, my assistant started calling out the kids to go to the toilet. and suddenly ayu got even sadder. i said to her "does ayu want to go toilet?"
her little face just lit up and she looked at me incredulously, as if to say "really?! me?!" it was one of the cutest things i've ever seen. i got her off of my lap and said "gogogo".
the rest of the day she was smiling and she was even saying "ayu happy!"
i told her mom that night, and i think she was relieved that that's all that was bothering ayu.
apparently, she hasn't yet actually peed in the toilet, but she does sit on it. and she's now so happy all the time. always running up to me and giving me a big hug.
and i can never get enough ayu hugs.
