I went with a confinement centre for my first and honestly it was good for peace of mind, especially since I didn't have to worry about cooking or cleaning, but it's quite pricey and you're stuck in one place. My second time I hired a live-in nanny instead and preferred the flexibility, though finding someone reliable took time. For the jamu masseur, my friend swore by hers from word-of-mouth referrals through her gynae's clinic, so maybe ask your PD or the hospital where you deliver as they usually have trusted contacts. The tummy binding does help if done consistently in the first few weeks, though realistic expectations are key lah, it's not magic but combined with proper diet and gentle exercise later it makes a difference.
You can try PEM Confinement Nanny agency ☺️ 4.9 stars and 6k+ reviews on Google is pretty amazing
