No, I'm afraid there isn't a specific NCT group for expectant mums - we tend to find that most expectant mums tend to be working until the last few weeks, so we haven't had a great call for it. Although you are of course welcome to come along to any of our open houses - quite a few of them are for 'bumps and babies' so you may meet other expectant mums. (If you are an NCT member you'll receive details of all of our events in our quarterly newsletter).
I have a list of some pregnancy activities in Forest Hill area, if you email me on foresthillnctrep@googlemail.com I can send it to you.
Also, once you've had your baby do get in touch as we run new mums coffee mornings.
