When my DGC were on the way, I was amazed to find that the free midwife-run antenatal classes we all attended back in the 80s were no more. There was some provision at Children's Centres in the most deprived areas, and the NCT classes, which had to be paid for and booked well in advance as they were over-subscribed. My DD and DDIL went to these, but I know other mums to be who missed out. I found the advice given at my classes invaluable, and I believe the lack of them must be detrimental to mother and baby health.
I must say I was also puzzled as to why, despite regular ante-natal checks, including one two days before he arrived, no one picked up on the fact that DGS3 would weigh in at well over 10 pounds, 3 pounds more than his brother. From what I've read since, this could have caused major problems during delivery.
