Any advice for FTM taking 6 month old to see Santa for the first time?

Any advice for FTM taking 6 month old to see Santa for the first time? I want this to be a positive experience for my almost 6 months old son. I’d love nice pictures as well but him meeting Santa in a happy and positive way is what is most important. We are scheduled for pictures tomorrow. I am going to try to ask Santa not to be too loud or get in his face since I know he doesn’t like when people do that. Any other tips or tricks?

Update: We saw Santa today! While he didn’t cry he didn’t smile either. The photographer asked if this was his first experience with Santa and I said yes. She suggested Santa offer to play with him with a teddy bear while I held him first. Santa also said let me use a quieter voice so I don’t frighten him. Santa has two young children at home, so he knew how to handle my boy. My son was very curious and grabbed onto his beard right away.

Got our pictures back already!
