Hi there; I was raised in Barbados from 4 to 17; went to school there and everything. It was a FABULOUS place to grow up! I was so lucky - what a childhood.
Pro's - Amazing education system turning out an extremely educated and skilled workforce. 98% literacy - all Bajans take education very very seriously.
There are private and government/(free) junior schools and the ultimate goal is to pass the 11+ to Harrisons College/Queens College (top tier) St Michael's/Lodge School/Combermere (Rihanna's old school) second tier. There are also a few private secondary schools, but everyone (expats and locals) tries for QC and Harrison's - these two school are over 100 years old and really traditional grammars. They are outstanding. I went to Queen's.
Barbados is known as Little England - it is strangely and adorably English in many ways - they were under English rule for 400 years. Their infrastructure works (not like Jamaica or Trinidad which by the way have terrible crime.
Life is at a slower pace and very outdoorsy - beach/sailing/water skiing/picnics/festivals all wonderful fun.
Barbados is very beautiful and although there is some crime it is a very safe place to live - safer than London!
The people are really friendly and helpful and just plain nice. Some expats choose not to interact and are cliquey, (as expats often can be) but it will be easy to make local friends.
The food is really good. The beer is really good. There is a fantastic carnival called Crop Over, and there are various other festivals - there is a Jazz festival too. Bajans like to dance, sing and party - and have a great attitude to life.
Barbados is very family friendly. At the private schools your children will make close local and expat friends.
Cons:- Food is expensive and the cost of living is high, due to having to import everything.
The summers are rainy, humid and hot (the winters are perfect).
The slower pace of life and smallness of the island gives it a bit of a 'villagey' feel in that everybody knows your business (even more so for the expat community). This can be a tad claustrophobic, (although it is nice to be part of a close knit community sometimes).
There is still a lot of colour consciousness - a hangover from the old days, which means that Bajan whites do not mix with the other races much.
And finally my pet peeve; the Government does not try to preserve the architectural heritage that makes Barbados beautiful and unique. Also they keep throwing up hotels that ruin the views and vistas I grew up with. Please join the National Trust! Lol!
Hope that helps!
