We had five of our grandchildren at our house for Easter Sunday supper and of course, an Easter egg hunt. I can just throw a bunch out on the lawn to keep the younger ones (two and fours) busy. The oldest is almost eight, and I had to level up my egg-hiding to challenge him.
This one loves to climb, so I used some tape to put one of his up high on the play fort. I’m not sure his mom was real happy about the altitude, but once he spotted it, he got up there with no problem.
A little more tape held some eggs underneath the deck of the play fort, just out of plain sight.
He quickly saw the one hanging from a tree with a pine needle pinched between egg halves hanging from an old bird-feeder hook.
The ones that stumped him? One was under an upside-down flower pot. Not hugely creative, but worked. The other was on the ground, under a pile of pine cones, with just the slightest hint of blue showing. I had to give him a couple of clues for these last two. Grandpa is still just a little cleverer than he is!
