So this is my 4th child, but my youngest is 12 and I had all 3 of my other kids before I was 20, so I never breast fed because it just freaked me out! I plan on breastfeeding this go round, I am 27 weeks and trying to choose a breast pump because since I am a working mom and need spouse to be able to feed as well - I would like to exclusivity pump if I am able to.. what pumps are recommended looking @ the spectra s2, medela or Lansinoh? Any advice please
