SUNSCREEN - Neutrogena Sensitive Skin is supposed to be safe for babies under 6 months. Available at Longs.
HAT w/ neck shield – don’t know where to get, but it's good.
SWIM DIAPERS – the washable kind are great, but you can also wash and dry the disposable swimmers up to 25 times!
BEACH MAT – Don Quijote has a great big one with a water resistant side. I got mine for like $21.
RASH GUARD – to protect and insulate. Evan’s rash guard is actually called “Sun Shield UV 50.”
BABY FLOAT – you still have to keep your baby within arm’s reach, but it’s nice to not have to hold them the whole time. And the kind with the sun shade is great.
SAND TOYS – shovels and a bucket is all they really need. But Wal-Mart has a sand toy package for super cheap.
