Mine has been dry since October 2023 but recently went through a couple of months of pooing himself EVERYDAY! Drove me mad! I had to have a word with myself not to get so frustrated but as soon as I chilled out about it he stopped doing it!
Mine was fully trained for 3 months then regressed and we are full on back into nappies again for the last 2 months. My friends daughter did the same and suddenly she started going to the loo again.
My daughter was potty trained last Christmas and I’m sure she had a regression half way through the year in May time? My friend’s daughter also did the same. They’re both back to normal again. Just try and be positive and praise her when she does it or go back to asking her more regularly again
