Advice for getting a kid's first striper?

[schoolie monster]

After some major sunfish action this past weekend, my daughter (almost 5) and her friend want to go out in the boat. Aside from me casting and hooking fish and then handing them over, what are some strategies for some bobber type fishing for kids?

My first thought was sea-worms... coincidently, my wife went to pick up my daughter's friend and I had her stop at the bait shop for some crawlers. She specified freshwater, but they gave her sea-worms. Other than having to run back to the house and try to dig up some worms while my wife took them exploring, no big deal. BTW, those things are creepy.

Anyway, I thought I could put those under a bobber and drift some mudflats... anyone no any good areas for that (in Boston Harbor)? Areas where I might get small bass/blues or even flounder or something...

And how long will those be ok in my fridge? Should I do something with 'em, or are they ok in there?

Aside from that, does anyone have any favorite techniques for small children getting their first shot at schoolies (or small blues)?

Thanks.
