I originally found this idea on Pintrest (of course!), although several blogs had variations of the same idea, some fancier than other. I went fairly simple, because, well, doing something consistently over a long period of time is not my specialty!
Starting on February 1, I woke up early, cut out a heart for each of the two big kids, and wrote something I loved about him/ her on it. (When the waking up early part didn't work, I did it while they were at school.)
Ruby discovered the hearts right away and bounced out of bed each morning to read what I had left on her door. Eli was a lot more low key about the whole thing. It was about a week before I ever even caught him looking at the hearts. Each one, though, in his or her own way, conveyed thankfulness for me having done it.
I will definitely do this again. Next year I hope to have all the hearts made in advance so that all I have to do is write something and tape them up each morning. That certainly would have simplified things!
Although this was great for Valentine's day, I think the idea could be incorporated at other times as well. The first thing that comes to mind is a heart with what you love about your spouse, one for each year you are married, during the month of your anniversary. I think this activity was even better for me than it was for the kids; it helped me put the focus on the fantastic children they are, rather than focusing with the slight irritations they might cause occasionally.
Sample "I love"s:
1. I love what a hard worker you are.
2. I love how freely you give hugs and kisses.
3. I love how original you are.
4. I love how flexible you can be.
5. I love how energetic you are.
6. I love how you stand up to bullies.
7. I love how appreciative you are.
8. I love what a good goal-setter you are.
9. I love how forgiving you are.
10. I love how cooperative you are.
