Yes, there's work to do. There's school to do. There are chores and dinnertime and whatever. But make sure that you take some time to focus on fun as a family! Here are some ways to do that:
Read
Take online courses
Play games (video games, board games, strategy games, card games, puzzles)
Watch tv together (this can be something fun like a tv series, or something educational like a documentary)
Create art
Take up a hobby together
Dance parties
Grow plants (plant a garden, work in the flower beds)
Build forts
Make a family memory book
Cook together and then make sure to sit down together to eat
Exercise (go for a walk or bike ride, yoga, follow an exercise video, set up an obstacle course)
Enjoy a spa day at home
Movie night
Picnic
Fly kites
Go on a treasure hunt or a scavenger hunt
I'm sure there are many other things we can do, so this is just a starter list. Maybe you'll find something here that really connects your family, or maybe you'll come up with something new!
