Eh, finding a good for January is quite last-minute lah, but don't worry, a few of us in Penang went through this and boleh still find good ones if you're flexible with dates! Best thing is to ask your gynae, or go through trusted agencies like those recommended by friends in your hospital's mummy groups, sebab they usually have screening done already. You can also put up a post in Penang-specific mummy WhatsApp groups or Facebook, honestly, word-of-mouth recommendations from actual Penang mummies who've used them recently work best, especially sebab you want someone familiar with your neighbourhood for sourcing ingredients and all that. Good luck!
