Potty Success

It is not my idea of good timing to potty train 14 days before the arrival of a new baby. Maddie however, has different ideas. She has been telling me for days when she has to potty and going in the bathroom and sitting, fully clothed, on her potty to make her stinkies in the diaper. Finally, today she demanded that I come take her diaper off. I obliged and she had a success. We made a big deal, she got a chocolate chip and was elated. What do I do now? Crash course and then let her regress after the baby comes or ignore her requests. Bad timing.
