Another fun way to grow your mother son relationship is to explore something new together. Visit a cultural or seasonal festival or a craft fair. See if somewhere around you holds a night market or a pop-up market where different vendors set up booths and you can discover all sorts of local small businesses you probably did not know even existed.
There are also all kinds of seasonal pop-ups to explore. Many local farms have baby animal days in the spring where you can do things like play with baby goats. There are corn mazes to be explored in the fall. In the winter, outdoor ice skating rinks pop up in many towns.
Museums are another great place to explore. Check out a local museum you have never visited or go to one of the rotating special exhibits at your local art or science museum. Sign up for museum newsletters or follow them on social media, and be in-the-know on all the new exhibits, free opportunities, and family days.
