prob a dumb question

Lovemylife • Mom to two awesome girls. 1 MC. Had my rainbow baby boy 6/5/2017!!!! So in love 😍
If it is I apologize blame pregnancy brain. So if this baby is a boy which I hope it is then me and my husband want a jr. I don't mind my son having my husbands first name. But in order to be a junior does that mean he would have to have his middle name too? I don't care for husbands middle name esp the spelling I don't understand why it is spelled the way it is. So I would want my son to have a middle name I choose for him. But would he still be a junior or does that kinda ruin it? I know I feel like this is common sense but my brain isn't working.
