A bit of background to my question: i am happily married and coming up to our second anniversary next month. We're both fairly young to be married with a kid (age 24) and our 3 month old has been refusing a bottle so I am trying him on a cup and hoping we can go out for a meal on our anniversary. It occurred to me that now I'm on maternity leave we might not have much to talk about other than the baby! (We both work in IT for the same company so unfortunately used to end up talking about work a lot)
Hopefully we've got a long happy marriage ahead but I do sometimes worry we don't have enough shared interests. The only ones I can think of are food/restaurants, wine, and watching Netflix! We both sort of like photography but he's more of a geek about it than I am. Other than that we sometimes chat about stuff we've read on the news. I get very bored when he talks about work or IT/programming, which is his main interest recently... 
What interests do you share with your DP and what would you chat about on a date?
