Re: preparing for second child, pump advice?
Are you planning on working full-time, or is this going to be a pump for part-time or occasional use? If you're going back full-time, then I encourage you to find a way to get a PISA. Maybe contact your local La Leche League? PISAs are supposed to be single user machines, but sometimes you will find a LLL mom who is looking to unload an old PISA "unofficially." if you don't think the APY is likely to work for you, then I don't know that the Isis IQ or Philips Avent are likely to be an improvement. I think they're all kind of the same range of machine.
