Is it harder/even possible to PT the younger sibling while the older one is still either in diapers or in training? We start DS1 on Friday with the help of the BCBAs. I'm scared. #1 of the amount of work it will be and #2 that it won't be successful. Anyway, we need to TRY, it's time.... and I figured it would be hard to PT the younger one if he sees the older one in diapers. I wouldn't say DS2 is totally ready but I hope in a few months he will be. Anyway, just wondering if it's a disaster for DS1 does that mean we won't be able to PT DS2 because of seeing his older brother still in diapers. I'm not trying to be negative or assume failure, I'm just curious.
