Between the Medela pump in style and pump in style advance? I'm looking at buying from someone a PIS Advance pump, it's the limited edition one in a nice bag. Looks like the motor's in a little pack that you can remove and stuff. Also, what about the Medela PIS Traveler? I currently have a PIS '98 and I love it. I like how both sides suck at once, are all medela pumps like this? I'm looking for another one to bring to work so I want to make sure I get one with similar suction etc to the one I have at home.Answer Question
Next question overall
Can someone give me ideas on potty training my son?
