A friend of mine is at Club Med Punta Cana right now and from what she's posted on facebook so far sounds like it is great for little ones (she has a 1 year old) and lots of programs for them.  Here is what she wrote:

We arrived to find a crib, stroller, fridge and bottle warmer in our room. And the room has two sections with a sliding door so kids can sleep while the parents watch TV, drink on their balcony. The baby club med is amazing too

I am looking to go with a girlfriend on a trip with our little ones. Both are a year and a half. I am looking for a baby friendly resort with daycare. I’m open to anywhere in the Caribbean. Cube, Dominican, Jamaica???? Anyone have a good one that they can recommend?

We are going to an all iinclusive in Jamaica that a colleague at work said was awesome as well as a  friend who is a travel agent and sent many clients with kids there who were all very happy with it.  Here's the URL

hello ladies

i feel i am an expert on researching family vacations as it has been the vain of my life the last month. Reading reviews after reviews just drives you nutty and 2 different sets of families can go to the same resort, the same time and have 2 completely different reviews.

Anyway, all the destnations that have been mentioned above, are great places to go.. not that i have been, just fron my research, but i found them all a tad pricey.

CUBA wasnt my first destination choice when travelling with the girls, but after reading the reviews on this place, and seeing how much cheaper it is - not to mention that my hairdresser just came back from there to with her family and loved it - i thought that i would pass it on.

We booked with Nolitours, upgraded to a sea view room and it cost us $800 (including taxes) and the girls are free - you have to love that.

happy vacations all

Jenn
