Rebecca, Hi and welcome to the Toilet Teaching board.
From personal experience I would say you should not have that much of an issue going back to PT. With my first DS we took many breaks for various reasons and each time we started back up it was easier. He retained all the previous times from training. I would suggest telling your DD that you are going to go back to using diapers only while she is sick, and then once she has recovered she will go back to underwear and using the potty. I hope your DD fells better soon. Please keep us updated on your DD's progress.
