Some of my past articles with lists of ideas can be found here, here, and – one of my faves, how about Christmas in July or August, among many other posts. You could also see if any of these would work for you – even though they were originally from Christmas. 🙂
My Facebook page, SandwichINK for the Sandwich Generation, is another place I post fun ideas I spot through the week, like here, here, here, and this idea via AARP. While you are there, be sure to LIKE my page as well as the post. 🙂
Twitter is another useful resource and you might enjoy this tweet and this one for the LEGO lovin grandkids. By the by, you don’t have to be “on Twitter” to read my tweets. Just go to twitter.com/SandwichINK to read them. 🙂
Finally, one of the BEST places for a myriad of fun ideas for all kinds of ages and interests is Pinterest. I’ve got a ton of goodies pinned to my boards, including Grand for Kids and Grandkids, plus all sorts of holiday boards. Pinterest has so many goodies to find you could easily get lost there. But don’t take too long – those grandkids will be here soon! 🙂
P.S. You might also stock up on craft and activity books. They’re often quite handy for our kids and grandkids.
P.P.S. When out at yard sales or shopping clearance sections, keep your eyes open for great prices on all LEGO regular and Star Wars toys and games. The older pieces may be easier to get at a great price and boy, are they handy to have when the grandkids need some quiet time.
