Agreed 縉媽.
When my son is newly born, I used Pampers. Frankly it is so expensive, even compared to formular milk. But my son can get all his required nutrition from the milk but diapers are thrown to the rubbish bin once used. Then I turned to Petpet (Size L is just around $75. just around $1/pc). I found it no different from pampers and nepia. Then my husband asked me why all mothers love pampers? Just because of the brand label?
