I'm teaching the boys manners in general but I do emphasize holding doors for women and standing when a woman stands at your table, pulling out chairs, etc.
Working on good general manners, kindness to everyone. He loves to open doors for everyone, and we have pushed him to open doors for baby strollers no matter whos pushing. His Iep meeting his teachers couldn't tell us how polite he was enough. He is the only child in his class who please and thank you all the time with out prodding.
We teach that you open doors for whomever is standing there, and give up a seat to anyone older than you.
I like this. DH is chivalrous (opens car doors for me, etc) and I know he'll want to teach our sons the same, but I'm more focused on general politeness and courtesy.
We just teach general politeness - please, thank you, hold the door if someone is right behind you (but not awkwardly too far away, which is hard to grasp at 3 - if he sees someone else coming, he wants to hold the door). We haven't made anything based on gender.
All of my sons knock themselves out holding the door for me. They learned that from their dad, not me. But I stand back and allow them to open the door.
They were taught at a young age to do that, but to also shake hands, etc.
