F.G.
I went through the same thing do not put her back in pull ups or underwear because that will give her an excuse to keep doing it, it may take time to get back to where she was just keep encouraging her to go on the potty. and keep pull ups and diapers for night time. trust me i have been potty training for years and many different kids and i have read all the books. good luck and just stay patient you dont want to punish her just remind her how yucky it is!! good luck and god bless!
