When she's holding him, say to her lightly and in a joking voice, "Sis you better put him on the floor before he gets used to being held all the time, I know I'm not planning to hold him until he's 6 years old!" And then laugh. This doesn't have to be a serious issue. Take a light manner with it so you don't offend her, and keep doing it until she gets the message. Chances are she'll stop holding him constantly here in a bit anyway, it might just be a new thing for her to be living with a baby right now and she's so excited she wants to hold him constantly. Your boy won't tolerate that much here soon either, kids reach a point where they want to be exploring on the floor and not being held.
