Would it be wrong to punish my 9 year old daughter for continuing to make skiddie muffins in her undies?

I find that some children never grow out of shitting in their underwear. As a mother myself my own son who is now coming up 19, I fully undastand and sympathise with you. He hasnt been able to control his bowels since he started wearing big biy underwear. I tried several punishments such as taking away his gaming consoles or tv privilages and even selling his beloved pet dog but i found it made matters worse. To be honest with you it does rather disappoint me that my own son is doing this embarrasing and most filthy act. Try making your daughter clean her own underwear and she if she likes that or better yet hide the dirty underwear somewhere in her room until she cant take the smell anymore and it trains her to get to a toilet on time. I will be trying this next with my own son, so I wish you all the best and would love to know if it works for you. :)
