suggestions for 1st beach trip w/ baby??

We're finally making it to the Jersey shore tomorrow with DD, who is 11 months old. I'm excited, but nervous- DD likes to put things (sand!!) in her mouth! But I think she'll love the water.

Any advice on what to bring, etc?

I've got an umbrella to keep us in the shade. I wish we had a wagon to cart all the stuff!

Thansk!
