I did the 'A Mother's Touch' class - 4 weekly sessions for $1500. Whilst I enjoyed it, and the baby did a bit too, I personally felt, reflecting once the course was over, that it was a hell of a lot of money for what it was. Basically a hand book of instructions and a mat and some oil to use at home, then session one learn how to massage legs (10 mins), session 2 go back over the legs and learn tummy massage (additional 5 mins), session 3 - repeat 1 and 2, learn arms and chest, session 4 - repeat 1-3 and learn face and back. In total it could easily have been completed in one session, in an hour.
All being said though, I did enjoy it and am glad I have done it. I think the idea of going to a group though is possibly to meet other mums and babies - you could easily search on you tube for the routines to follow without the cost.
