Our daughter Tina (Name changed) is autistic and started going to a Day Hab Center here in town. There she made friends with a group of three other girls around her age and has been REALLY Blooming. THIS IS WONDERFUL for her! However her best friend Sam (Name changed) has the mental capability of a toddler even though she is 20. She is not potty trained and wears diapers. After becoming friends for a couple of months our daughter Tina is now hanging out with Sam all of the time at the Day Hab. And doing everything Sam does, including wetting and filling her pants regularly. At first just at day hab, now its at home, and everywhere else. She doesn't care if shes wet or soiled. She was potty trained at 11 and is in control of her functions. I was hoping this was a phase, but it its gone on for over 6 weeks. I was going to pull her out of the Day Hab, but shes made friends and is doing great in other areas so we wont. We did stop taking her for a week or so, but she made NO EFFORT to use the bathroom the entire time. When we talk to her, she says she wants to potty like Sam. The day hab center has been very patient and has changed her, only to watch her wet and fill her pants, again and again. They have told us that if it keeps up she will have to wear diapers or pull ups while shes there. I also spoke with Sam's mother who has attempted to potty train Sam numerous times with no results. She says Sam doesn't mind being in diapers (wet or soiled) and has never shown any interest in using the restroom. So Sam will not be using the toilet any time soon. It seems cruel to take her away from the friends, she loves to be with (If this will even solve the problem), but should we just put her back in diapers? It looks like diapers may be the solution if she wont stop, we cant have a 21 year old wetting and filing her pants everywhere she goes. We will try any good ideas. What would you do?
