ei-ya, but only Avent disposable bag can be pumped directly from Avent manual pump. If use Gerber, need to first pump into the bottle and pour into the milk bag. There will be so many things to bring to work. Besides, the Gerber milk bag is more expensive.
My baby will be born next month. Need to look for more Avent bags then.
荷花有得買, geber without ziplock. I think it is simiar to avent. I just bought two packs. It is 35 dollars for 50 bags. I think it is quite cheap compare to the other bags. I remember I bought the medela bags at the beginning because I don't know I can use avent and buy the clips from Ikea.
