A very good baby group is held on Tortola twice a week, Tuesdays and Friday mornings in a church past road town, east end. (i do not know the name of the church, sorry)
I also have a baby 8 months, if you can send me your email address i will forward you the contact details of the person that runs the group, would also be great to meet you both.
Let me know if you have any other questions.
