i have two contacts for malay massage ladies, and have used one of them for my two post-natal massage. the one that i enagaged perform traditional massage and binding with additional services, i.e. to sit over a pot of "charchoal" like a sauna thingy - was told it would help to shrink your uterus back in shape and to get rid of water retention in your body. she also helps to massage and push your uterus back to the original position...apparently, it was very effective on me as i got a good result from my post-natal checkup with my gynae within 7 days for my two pregnancies.
nevertheless, the purpose of such massage is to get rid of the "wind" and "water" in your body and relax your body, and not really getting rid of your tummy fat. at the end of the day, you still need to watch your diet and exercise...
pm me if you want to get their contacts.
