Poor kid. Poor mama! The PP had some great ideas. My DS1 is a bit younger, but here's some thoughts of stuff that works for us (we're pretty much TV free, although DS may occasionally watch a a movie with me when we're both sick):
* If DS1 isn't feeling too awful (low fever, no GI, etc), we take a walk outside. Not to the playground, etc., but just out & about for some gentle exercise & fresh air. (For DS1 it's one of the few times he has my undivided attentnion - with DS2 on my back- so he can talk & talk to me).
* We play cards. I teach DS a new card game from my childhood -- right now we play a lot of crazy eights...maybe your son would play a card game you taught him, something new...I'm thinking "I Doubt It", speed & spit, cribbage, even poker!
* Try some physical contact...mama touch is very healing. Rub his back (even if you're just putting on vicks!), his feet or his head.
* Find other ways to be 'indulgent'. Make yourselves chai or special tea. Run him a warm bath with healing essential oils. Clean flannel sheets. Give each other pedicures
, whatever will feel special, indulgent & nurturing.
* I'm big on crafts & so is DS1. If your son is amiable to it, try to think outside the gender guidlines...teach him to knit! There are lots of cool kits out there - DS1 just finished a 'make your own birdhouse' kit. I gave my 8 yr old nephew a bok of advanced paper airplanes, kept him completely occupied for an entire day.
* Books on tape/CD!!!! Rent a bunch from the library, even things he's read before. Books on tape save me when DS1 is feeling lousy & I need to be free to take care of DS2, cook, etc. While your at the library, grab a bunch of books, get a wide variety, fiction & non...you never know what might grab his interest.
--hope he feels better soon!
