“My husband does not help.” It almost sounds like you don’t live together. If you asked for some help would he help you?
I believe temper tantrums, stubbornness, and occasional potty accidents are normal. I don’t believe urinating on the carpet is normal at all. I would have a heart to heart with her, without anger and tell her you understand how she could get a little urine on the bathroom floor, but when it happens she needs to be the one to clean it up. Put a roll of paper towels in the bathroom. You may have to clean it better later, just don’t let her see you. Make her responsible for her own messes.
As for the carpet issue, tell her if that happens again, she will have to wear pull-ups until she can get to the bathroom in time.
I accidentally broke a window when I was about three or four wearing my mother’s high heels. I kicked one off and it flew through the kitchen window. My older brother, who was 14 or 15, told me I would have to pay for it. My mother wasn’t home at the time, so I was pretty scared, worried and at a loss as to how I would ever pay for that window. Needless to say, I didn’t put on my mother’s heels anymore.
Blessings……
