Hi A.,
Transition is so hard for little ones. She is dealing with school, a teacher, a sibling and one on the way.
Have you tried a reward system? my stepson started pooping his pants in k. We got a box for us, his teacher and both sets of grandparents, we made a chart and gave one to everybody as well, every two days without an accident meant he got a prize from the box, no matter where he was.
Maybe a little alone time with just you or dad would help too.
When I was expecting my second I tried not to change anything for my two year old. She was expecting a sister and moving into a new house. She was 20 months when we moved and 25 months when her sister was born, still using a binkie, carrying a blankie and not potty trained. It drove my family nuts, but she was happy. She will be three on Nov. 15, is potty trained, no binkie, no blankie and happy as can be!
I know it is frustrating, hang in there and try to remember where she is at.
