Hi Huilim, I highly recommend postnatal Jamu massage by D'Happy Mummies, you can check out their fb page: dhappymummies. My Sister in law recommended to me and I've tried them, really effective in removing my water retentions and giving me back my flat tummy after delivery. They use oil instead of herbs, thus safer for sensitive skin. They will provide a binder to help bind your stomach. Theirs is $85 per session, really affordable as compared to others.
