hello donutmum, just come across your thread, not sure whether you will still be checking it, but wanted to say that there are a fair few baby groups -
dilman club has bumps and beyond group on sat and thurs
rugby club has sticky fingers on mon and wed
chaoss gym has various groups
softplay group mon and wed
british club also has a group and there is one in awali (not sure of venue)
musical babies group, various mornings, need to sign up for a term of sessions in advance
am sure there are more that i can't think of at the moment as well. if you get your husband to pick up a copy of bahrain this month, there are listings with the timings of some groups in there.
i agree with starmummy that it is like a bunsen in july/august but one thing to bear in mind is that ramadan falls in september this year which might not be the greatest time to move over if you can avoid it as all the restaurants and coffee shops are closed during daylight hours, which will really restrict you being able to get out and about when you arrive.
hope this helps. anything else you want to know, i'll do my best to answer!
