I wouldn't leave your DS alone with FIL if I were you. Children learn by example, they copy our behavior. We taught our DD manners by modeling, using polite phrases when talking to her and each other. She was saying thank you and your welcome before she turned two. She also smiles at and greats people (something I do). She's just started using please alot, all the time lately, at 3.5. And she says 'I'm sorry' abit too much but so does my DH.
Trying to force LOs to be polite by being rude to them often leads them to becoming a rude adult rather than a person who's habitually polite. Being surrounded by polite people who respect you makes politeness seem natural. It doesn't sound like your FIL understands the value of respecting LOs. I wouldn't trust him.
