I highly recommend the Ameda Purely Yours pump. I am still pumping 2x daily for my 10 mo old baby boy. I absolutely love this pump. I am currently using one that my coworker lent to me and it lasted through 6 mo of her pumping and 10 mo of my pumping (so far) and is still going strong. I still usually am able to pump more than my baby eats daily in 10 minute sessions (previously 3x per day, now 2x per day). The Ameda pumps are not as widely available as the Medela pumps and thus are not as well known, but they are cheaper and just as highly rated from sites when buying a pump. After using both, I think the Ameda pumps are actually easier to use and clean. The design is brilliant and there is absolutely no way for the milk to get into the tubing (thus no worry about borrowing pumps). You can purchase the pump with a carry all, backpack or alone, depending on how much you want to spend. Also, according to Baby Bargains they have also repackaged the exact same pump and sell them at Target.
Also, with all due respect to your doctor, they generally don't know much about the practicalities of breastfeeding and certainly don't study that in Medical School. The first month is critical to establishing your milk supply, so I wouldn't have your husband feed a bottle at night until your little one is at least one month old and even then, I don't think it is very helpful since you will probably have to get up to pump anyway. While it is important to stockpile a supply for going back to work and getting familiar with the pump, give yourself a break for a while and don't worry about that yet. You have plenty of time. Good luck and if you need advice, you can always contact your local La Leche League (www.llli.org). Leaders and members are always available for great advice.
