I'm due this June and planning on BFing. I BF'd my daughter who was born in 2004 and when I went back to work I used my Ameda Purely Yours and it worked great - I pumped for almost a year before finally retiring it! So my question is for this baby do you think my pump will still be as good? Or should I look into investing in a new one since it has been 4 years and I did use it for so long? I have no clue what the 'lifespan' of a pump is so I'm not sure what I should be doing!
