The Medela milk bags allow you to pump directly into the bag, but for other brands, you need to pump into a bottle first and then pour into the bag. Personally, I think the Medela bags are too expensive (> $6 per piece). I recommend Boots milk bag. You can get them at Baby Outlet ($68 for 40 bags). In Thailand Boots, it is so cheap, just 120 Baht. So if you have friends going there it will be good to ask them to buy for you.
我隻隻牌子嘅storage bag都用.. depends on 邊個brand on sale. 所有牌子嘅storage bag, 都差唔多, 返而小用medela storage bag, volume 太細, only 入5-6oz.. 而gerber, the first year, lanolish(spelling error??), avent, playtex.. all of them 都好用同volume大過Medela.
Gabriel 巳9months, 我return to workforce 都4.5月.. so far.. Medela pump in style advanced works excellent on me.
你加油啊
