Hi ladies,
You can try Chinatown also. The market beside OG. I think 2nd or 3rd level they got a few shops that sell pyjamas that shouldn't be too ex. Based on my personal experience, I bought 2 types of PJs, 1 is the pants and button down top. The other kind is like a dress kind all the way to ankles or calf. And its also button down all the way.
Based on my own experience after delivery I find the dress with the front button down is most useful, I had natural delivery so stitches were quite painful during 1st few days. So if you wear pants, have to bend down pull up ur pants can be quite taxing. Whereas if its a dress, you can just pull up. Then button down easy for breastfeed also.
But I only wear it during hosp stay, once I reach home its t-shirt and shorts for me. I don't normally wear PJs.
Also buy something more "presentable" for hospital stay cos alot of relatives/friends will come and visit, and I also had to wear it while walking around the hospital to take my baby to my room or to attend the post natal classes conducted by hospital.
