Would you bring your 3 month old out for the fun of it?

An

So my son loves stimulation. He doesn't really over stimulate (or hasn't yet at least) and constantly wants to people watch, see lights, sounds, etc. If we go out to grocery shop or a restaurant he has to be out of his carrier to look around. This weekend when we were away at my parents house he had a blast and was so so good. He only cried maybe once or twice the whole 4 days when he was hungry! But as soon as we got home he started being fussy again and I'm wondering if he's bored here. I've tried all the toys and activities we have, but at 3 months he can't "do" much. My husband suggested bringing him to stores since Christmas stuff is out and he might like looking at all the pretty decorations and the what not. But would that be too much?
