How often should I get my nephew

If your brother lived a few hours away and has a son in the same city as you, how often would you get your nephew?

Also just want to say, my brother does see him too. He comes down every 2 weeks and gets him a few days.

Anyways, he asked me why i never pick him up when he’s gone. I usually just see my nephew when my brother is here. I told him I would try to get him more often.
