Hi JC,
Unless you want dodo everywhere you and your mom have to be very firm. That means upsetting your daughter and putting down limits. I would go in first and get everything out and then let her finish the job - whether she likes it or not. The reason? Some forms of do do is so messy and smeary (is that a word?) that it can get every where. Also there was an outbreak of some disease in the Riverdale, section of the Bronx due to this. It happened in a daycare center due to the wee little ones not wiping the way they should. It was on the news it spread through out the community, in families, schools etc. People were ending up in the hospital. The wee little ones get it on their hands or toilet handle or clothes and spread it by accident. Everyone in your household could become sick and end up in the hospital. She is only two - I can assure you - no matter how hard she tries she will not wipe correctly.
At the end of the broadcast the newscaster said, "The cure? Wiping correctly and washing your hands afterwards."
Another aside. A teacher said a child was coming to school with such stinky breath. She didn't even want the boy coming to her desk to ask a question his breath was so bad. When talking to the mother about the situation the mother said, "Yeah, he gets so upset when I try to brush his teeth I leave him."
That's parenting today.
Good Luck and congratulations on a fully potty train little girl. My daugther was fully potty trained at 2 1/2 as well.
