Children do not understand what is really expected of them
when potty training is taking place until they are about 3
years old.
My mother insisted she had me potty trained at 9 months - I
told her she was the one trained !!!
I would suggest you put diapers back on her, do not mention
using the toilet, and in the spring when the weather is well past needing coats and heavy slacks, then pick up on the potty training again. Bet you it will work that time !!!
