Hi dino,
I bought 4 different brands of maternity pads.. ;p Whisper Heavy flow and overnight 28cm, Sofy Nightsafe side gathers 35cm, Kotex Nightsafe 28cm, Kotex maternity adhesive 28cm, Dr P maternity pad 37cm.
Many pple said just buy those heavy flow for night is enough. I personally feel Whisper heavy flow and Sofy 35cm are very good. I dun like kotex. But some pple say must get maternity pads as they are wider - meant for really heavy flow. So i also bought kotex maternity pads and Dr P to stand by. But kotex dun have wings; Dr P 37cm (wow!) so i try.. hehe.. If really better, may ask hb to buy more during maternity period.
