Long names

I know it's common for multiple last names but what do you ladies think of multiple middle names?

I've been on the fence about my son's name for a bit ever since my fiance and I have decided that his name will most likely be Jaxson. However, he likes Griffin as a middle name and I like Riley. He brought up just using both which I'm not completely against but I don't know. It seems like it'd be a lot. Jaxson Griffin Riley then our last name.

Has anyone else named their son with multiple middle name like that?

I mean I just don't want it to be a headache for him when he gets older and has to put his name on legal documents and such.
