Been going to Antenatal exercise class since early on and they have been v good, mixing a bit of exercise with a common sense chat about anything and everything.
We have parentcraft classes starting in a couple of weeks. One woman at my antenatal went to her parentcraft and they got condensed from 4 weeks to 2 and consisted of watching some dodgy 80s video. At the end of which the midwife said "right, that's how we used to do things then. These are all the things that we no longer do...."

Plus she freaked her out by telling her to take her baby sleeping bag thingy back to the shop because it was "dangerous".
Ours are supposed to be geared towards multiples, so we'll see how useful they are....
