I too have attended free sessions for some of the local music groups and have never felt the need to go for a full term... I cannot remember who said it but i was shocked that at one of them no one even asked the name of the children there, just got straight into the class and then seemed to be auditioning for cbeebies... Personally, I now give them a wide berth (Trish- just so as you know i am not classing you in the same category as the monkey/ caterpillar music types). Last summer I did attend mother and baby yoga classes at Brockwell Lido which i will admit that I was doing more as a get out of the house thing rather than a genuine desire to do yoga but found that they had a good way of paying where you had to buy a block of 10 classes and were given a card but they could be used as and whenyou pleased so if you were away for a couple of weeks for baby or maybe holiday reasons then you did not feel you were wasting your money.... My favourite place is Peckham soft play as for ?1.35 for a 50 minute session I think it offers genuine salvation and value for money and we can sing and dance at home.....
