I am expecting my second baby at the end of April, and would definitely be interested in meeting up.
Forest Hill is a very active NCT area and I know from last time there are many coffee mornings organised at new mums houses, so I am going to renew my membership so I can take part. If you are already a member (you will automatically get membership when you sign up for the classes) you should email the area rep, and then you will get a weekly email letting you know what is going on. It's a really great way to get to know people close by.
PM if you want to meet up beforehand, or want any more advice on baby classes/groups (I pretty much tried them all last time).
Look forward to hopefully seeing you over the summer!
