I chose NCT purely based on class times. The thought of going to a class from 7-9 after a long day at work filled me with dread and NCT offered a two day ?crash course?, which was great and I was lucky enough to meet some lovely people too. One other thing to think about is proximity, a few people in our group missed out on classes in their local area and had to look further afield. It meant that all their new ?mum? friends lived miles away and they were constantly travelling around with a young baby. Good luck with your decision
