We've been trying to do this more, but it's not easy! The most consistent way for us to do it on weekends is for one kid to have a playdate with just their friend, and then the other kid goes with a parent on some sort of 1:1 activity. This weekend Bee is taking our daughter to a playdate, and then my son and I will go to IKEA together to buy a stuffed animal that he lost.
How often do you spend time with each kid one-on-one? (Outside of stuff like bath/bedtime, etc.)
