Put a note in their lunchbox.
I like to put a little note in with my son's lunch. Notes are great for kids who aren't that into reading because they're short, they're fun, and they're from mom. I keep my notes to the point, and very upbeat. Something like: "Hope you had a great morning. I put a treat in the outer pocket. Enjoy! I love you - Mom xoxoxo"
I don't tell him to eat his veggies, or remind him to check the lost-and-found for the mittens he lost. I want him to look forward to my little notes, and that's good "reading reinforcement" behaviour. When what they're reading is fun, they'll look forward to reading.
Check out these Crayola "mini lunchbox messages" I found at a Michaels craft store. They even have a little envelope. But of course, any piece of paper will do - and don't forget the xoxoxos.
I've got a call in to Crayola, to find out if you can purchase these notes online. When I hear from them, I'll let you know. And yes, I did photograph this on top of snow. Tres Canadian, n'est-ce pas?
