If your kiddos are still virtual schooling, why not make it comfortable for them...which in the end makes life easier for you.
Number #1:
Get a Comfortable Seat Cushion or Chair
Your child will be able to focus more if they're comfortable. A great addition is a comfortable seat cushion. Top brands include: Purple Seat Cushions, Trideer Inflated Wobble Cushion, Kore Kids Flexible Seating Stool or Turnstone by Steelcase.
Number #2
Consider Blue Light Protection
Too much screen time can put a strain on your child's eyes and may be linked to discomfort - blurred vision, dry eyes, and headaches. Some tips to limiting exposure: take a 10-minute break at least an hour between screen time, dim the screen to 60% or invest in a Blue Light Screen.
Number #3
Plan & Prep Healthy Snacks
So hunger isn't taking over focus, ensure you have healthy portioned snacks prepared for quick grabbing throughout the day. Protip: use reused clean yogurt, cream cheese or spread containers as a sustainable option.
Number #4
Create a Great Space
Clutter can affect a child's stress, anxiety, sleep, and focus throughout the day. Ensure their learning space is tidy and in an alternative space than their bedroom. A great book with tips for you and your children is The Life-Changing Magic of Tidying Up!
