Wow, talk about a deep subject.
I'd like to chime in with my two cents if you all don't mind. I'm a Summer Camp Director and Middle School Teacher, that's worked as an Assistant Therapist in a Play Therapy program that has quite a bit of kid experience, though I will openly admit, I'm not a parent, yet.
With children it's important to have boundaries and clearly defined roles and boundaries. I'm not going as far to say that going against the norm is a bad thing but it does have its repercussions. Being a kid is tough enough knowingly adding another thing for them to come to terms with and deal with. Imagine having to go to middle school and have the other kids find out your parents wear diapers. I cringe at the thought.
On the flip side I can understand your stance. I'm gay and I know that when I do have kids that too can cause them extra baggage so to speak and of course I'm not willing to sacrifice that portion of myself for anyone, not even my children.
I think you'll have to ponder the situation and weigh it carefully. I know diaper and my AB lifestyle will be not hidden but kept well away from my kids.
