They only do them at City. It only took a week or so for them to reply.
You will probably hear something soonish as you are now 26 weeks and that seems to be the time they start, i was a bit further on as i didnt apply till late.
If you dont mind paying for them then there is another one i am going to starting next week called Babycoaching, they do day courses for £80 or 5 week courses for £150 but if you are lucky you might get the 5 week course cheap like i did.
