Binder and compression stocking

I recently delivered in KKH, after delivery they did asked if I want to buy compression socks from them which is not cheap so I didn't buy from KKH as I alr purchased cheaper ones online from shopee. They also say that as long as the ones I have are categorized as compression socks, it will be okay to use them also. It is good to use a belly binder right after birth but it is also okay to start binding your belly when you start your post natal massage. As you can continue to bind your belly for months even after your delivery. The longer you bind, the more it will help to shrink your belly size
