C.J.
I give my 3 year outside activities to do & it keeps him busy forever!
I purchased a book that gave me lots of ideas & here are a couple that I can remember.
Car Wash - Tear Free baby soap in buckets to wash everything in site outside - starting with my car of course!!! This always moves on to his toys, wagons, tractor, swingset, picnic table, etc.
Fence "Painting" / House "Painting" - Another bucket of water and a big paintbrush so he can paint designs with water on anything he pleases. Once it dries he can start again.
Bug Finding - Found a bug container at the dollar store and we search for the smallest bugs in the grass. This is TOTALLY gross for me, but he's a boy so I'm trying to get over it.
Kites - Who doesn't love a good kite? I'm still practicing this, must admit I stink.
Swingset - It sounds like at the ages you have you could make a wise investment and it would payoff over the years!!
Sprinkler - We play in the sprinkler almost every day and I have fond memories of doing so with my own sister and mom. Not to mention the photo ops!
Picnic on the lawn - I know when you go to Grammy's house you tend to eat around the table, but every once in a while it's fun to break the rules and eat outside picnic style.
My mom has theme days for all of her grandkids - Cowboy day, everyone gets a hat & eats cowboy food and plays cowboy games (ALL DAY), Hawiian Day, for the girls mostly but grass skirts, ham & pineapple, Circus day with clown theme, popcorn & hotdogs, etc.
It sounds like you are very involved & that's wonderful!
You are SOOO sweet.
Good luck,
C.
