Medela is very good compare with pigeon.
You may thank that what is the difference between those electric pump, it seem the same.
But Medela is different.I brought one from Mannings
($649) and find out it is more comfortatble, and can pump more milk without painful! Since I also in doubt of my milk supply, and I found out the main reason of less milk is the pump. I highly recommand you yo buy a new Medela , it worth to buy!
我剛剛買了個Medela mini electric pump, 可惜產量不及Avent 手pump(少一半, pump唔清), 有無人可以教我用Medela mini electric pump???!!! 買個軟膠cushion加係pump 咀 (好似 Avent's let-down massage cushion)有無用呢??? ^0^
I think you have to check if the cushion (small white parts) is tightly fitted at the edge, if it can make the "paa paa" sound, then it will pump up easily.
