For many parents, the end of the school year does not mean the workload has changed, but it does mean that your mindset needs to change.
Try to find time each day to do something with your kids one-on-one, even if it is just for a few minutes.
Things like:
Race to see who can build the tallest tower
Solve a puzzle
Watch an art video and follow along
Go through a cookbook and let your kid pick out a recipe
Do a family yoga video together
Use this summer to bond more with your kids, they had a hard year.
