Is my friend ABDL?

I have a friend that I told recently about how I like to wear diapers, he was very accepting about it and just said Ok thats a bit different but cool, then proceeded to tell me a few of his kinks.

I have recently noticed he often posts pictures of him with teddy bears, often wearing a onsie and talking about Pokemon/cartoons etc.

I was wondering if he is ABDL and is perhaps also padded up. I dont think I would ask him as firstly if he wanted to tell me he would; and I also know that just because he posts pictures like that doesn't mean he is ABDL. What is everyone's thoughts?/anybody else thought similar about their friends?
