Potty training regression

Amanda

My 3 year old was consistently going 1&2 on the potty by 2.5 years old. Suddenly instead of going 2 on the potty she’ll just go hide and come out a minute later smiling saying “somethings in my pants Mama!” Like she’s proud. We’ve tried stickers, taking her to potty at consistent times (she’ll refuse to go), and we’ve even tried bribing with chocolate and nothing seems to help. Anyone have advice?!
