Eh, this is super important, kalau pump size tidak match, memang sakit and boleh damage puting! A few of us tried different brands and the game-changer adalah finding the right flange size (the part yang langsung touch the breast); kalau terlalu besar or kecil memang akan sakit. Some mums swear by Spectra or Philips Avent because diorang design lebih ergonomic, tapi honestly the best way is either try before you buy (some shops allow this) or check if your lactation consultant boleh help guide you on the right size, they really know! Also jangan pull the suction terlalu high right away lah, start low and build up slowly.
