Hi
My brother Tim who is a professional photographer visited a couple of my baby yoga classes recently. In a very relaxed way he took many informal pictures just as the class was in progress. the results are just lovely. the parents were delighted and he received a huge number of orders for prints. I had suggested the idea to the class a week beforehand and made sure we had written permission from everyone. it was in no way disruptive, he is very sensitive to the atmosphere but manages to get quite individual photos as well as some group shots. Tim is based in london but is willing to travel if you are interested in a visit to one of your classes. he charges very reasonable prices for prints of varying sizes. the photos will also be very useful for you advertising and website too
His website is 22 photographic to see some pictures and to get in touch with him. alternatively do email me for any further info
hope the idea is of interest to ou and your parents
best wishes to all
Sally
