Warning: potentially annoying pontification to ensue.
I believe it is important to instill your kids with the importance of community obligation and compassion. As I wrote previously, it’s too soon to do most volunteer work, but a beach clean up is just right for a 3.5 year old.
We had a great time. Between playing in the sand and surf we picked up trash and talked about the importance of helping others and making the community we live in a better place. Ashby responded with: “like heroes”. Exactly.

This is a great way to teach your kid a lot of good things, nice post!
That's a great lesson for a 3 1/2 yr old. Aaron. We all need to be better stewards of our beaches. Some seem to believe the beach is like a movie theater where you can throw trash on the ground and someone else will clean it up.
