>Whispers< Why only black mums? Might be lots of all colour mums that you could make friends with! Title sounds a bit off, imagine if it was any white mums, wouldn't be acceptable. Hope you make some new friends though!
I also know how you feel. Not many black mums around my part of barnet,compared to Tottenham where I use to live - it can be isolating. When I visit the parks or parent groups, often feel I don't have much in common with the other mums. If they go themselves - it's usually nannys.
You might find the multicutural section helpful- there's meet ups there also.
