I brought a beaba sterilizer+warmer.. bought drinking water from supermarket and make hot in one of the bottles to fill into my thermal flask.
I brought a packet of diapers, extra sets of clothes (we take 2 sets for each day). I think we brought around 5 bottles, then snacks. 😅
We sticker mostly to malls in bkk though. But when desperate time calls, stroller or anywhr which is flat.
Platinum mall, t21, central n siam all have nursing room if i not wrong. The mall near jodd fairs i tink also have.
Hope this helps!
