Potty help

💕

So my 2 year old is not potty trained, but she practices.

She’s done this same thing 3 times in the last 2 weeks. She sits in her potty chair for awhile (just to try), and within 30 seconds of her getting off the potty chair she ends up going on the ground. She kind of whines when she does and looks at the ground. I think she doesn’t quite get that was her going potty

I explained what happened after, is there anything else I should be doing? Or does anyone know why she’s doing this lol?
