I can relate to this as well! Lots of good info has already been posted. I agree that it doesn’t have to be a lot of time each day, but it needs to be dedicated to them (with no distractions including cell phone). Some things I enjoy that feel like bonding time: going to the library and reading, baking, shopping for a recipe or getting their help picking out a present for a friend/family member, setting up a sprinkler or yard games, spending time at the pool (where I actually get in and play too), painting by numbers, origami, going to the zoo/aquarium, and I was gifted this activity book and love it: https://a.co/d/49jxSLy
