Barbados with two young children

Hi there! Going to Barbados in March and curious if anyone could recommend a beach that would be good for two little ones. Something with some shade or where we can rent an umbrella to keep my fair little boy out of the sun from time to time?

If not beach, then any other activity.

Thanks!

Boatyard, Harbour Lights or Lobster Alive are all a short cab ride from the port and offer chairs, umbrellas, and good facilities plus food/drinks.

Can anyone recommend a tour (probably half day) for a family with two small kids (3 and 5 years old)?

we did the submarine with a 3 and 4 year old... it was a great experience. Atlantis submarine- I haven't looked into it for a while, so I don't know current pricing or anything. They say on the website you have to be able to climb down the ladder unassisted, but they were really good about just handing down the littler one. Each person sits in front of his/her own window, and you really see a lot. We have done this in both Barbados and Cozumel- it's not cheap, but a really cool experience.
