I am a grandmother looking after a very active 7 year old with ADHD. I find going outside helps, as does the playground (now that they are open in my area). I have a small ‘exercise’ trampoline for her to jump on. Screen time limits have gone out the window for learning shows and games (e.g. education.com; ABCya.com; knowledgekids.ca; tvokids.com) She has also enjoyed making art with the shapes on Powerpoint for quite a few years.
Honestly, if your child is healthy and feels loved, you are doing an amazing job. Give yourself a break!!! NO SHAME!
