We're about to have our second kid in spring so that is the biggest thing to look forward to. In prep for that, planning to switch out our sedan for a minivan (due to 2 carseats).
Apart from that, try to keep learning. Pickup something new I didn't know, last year it was chess, this year haven't picked anything yet (maybe swimming).
Most reasonable recent sedans have two or three isofix points, so I do not see the need for a van when you have two kids. The difference in handling and refinement (noise, cabin quality) is quite large, although the extra space is nice.
