My dd has been pulling her nappy off so I have been putting her on the potty and she has taken to it well. We have placed a potty in her bedroom during the night however she has taken to drawing on the walls carpet toys with faeces and wee. We have tried taking the potty away, doubling on clothes which she pulls off and even put her nappy on back to front but she pulls it off. Any additional advice would be great I can't think of anything else to try and stop this behavior.
