I have a newborn niece by my brother-in-law. His fiancee also has two young boys from a previous marriage. I am looking forward to opportunities to build my relationship as an uncle with the boys. My brother and husband both don't want kids, so it sounds like this will be the only real chance to have a close family relationship with Generation Alpha.
Interestingly, they are into a lot of the card games that were popular when I was a kid like Pokemon, Magic the Gathering, and D & D. We are thinking about giving them a trip to a game shop for Christmas and some money for games.
