Just because it's not Thanksgiving anymore doesn't mean we should forget about trying to model being grateful to our children. That's why my husband and I have started using these bucket fillers. Our kids saw us using them and have since been "playing at being kind".
We got the idea from Mrs. Bond's First Grade Class: a 'bucket filler' is someone who makes other people feel good about themselves, either through affirming words or actions. At the end of every day, Mrs. Bond gets her students together, and they talk about how they filled someone's bucket that day, or how someone else filled their bucket, and place pom-poms in their 'buckets' as a tangible reminder of this.
I think it's very adaptable to a home setting. In our case, we have been using transparent cups. We decided we would use it for things we liked about ourselves too. For instance, the other day my husband made a very nice dish for dinner and went to put a pompom into his own cup. He likes that he is a good cook. Our kids have started doing this game too now, and have been leaving a lot of love notes in each other's cups as well as ours. I really like the idea of them being able to see physically what filling someone else's, or your own, cup means.
