My DCs are 9 and 6. I'm glad this happened at tjis stage in their lives rather than earlier on, although would love to be back to normal.
They can get dressed by themselves, eat breakfast without fussing, eldest can run a bath and they can both wash themselves and brush their teeth. They just need nagging to do it.
They have longer attention spans than tiddlers and will sit and enjoy a whole film.
They have Lego, craft sets, colouring etc which will occupy them for some time. Board games too. They enjoy baking with me and caring for our pets.
They are able to use my phone with supervision to video call family members and friends, or write them a letter or email and read the reply.
They understand basic hygiene and how germs spread, so accept why the park, cinema, cafe etc is closed.
They have school work to get on with which takes up an hour or so each day and adds as one structure. I let them play on the xbox as well though.
It's still sad for them. I teach at their school and their classrooms were such finely tuned places of purposeful learning, with all the daily routines in place. It makes me sad to think of the classrooms empty with all their work still on the walls. Their friendships are suspended for a little while.
We are lucky to have a garden and fields with horses (not owned by us but on the doorstep). I'm not working so they have my at terr. There are times when they are grumpy and sad, don't want to do school work, they bicker sometimes, they resist the daily walk and can be oppositional because they miss their normal lives. But I think if they were younger we would all struggle more.
