You sure do have a lot going on!!! wow.
Ok, any kind of electric or motorized breast pump is constructed so that the milk NEVER gets into the motorized system. That would cause a shock. The manual ones are designed differently but still you can replace the parts and sanitize the whole thing. While the electric/ battery ones are reuseable, I would look into getting new hoses and plastic parts as priorly suggested. Make sure everything that can get wet is sanitized and don't worry about the "disease comments"...
Yes, it is/would be nice to have the "tops" of pumps... But is not necessary. I have 3 kids and am 20 weeks along with my 4th. I did not use any kind of pump regularly until my 3rd was in the hospital when he was 4 months old. If you are planning on stocking your milk so you can go back to work or leaving your baby for a few days for a vacation it makes sense to pump all the time. But if you are planning on more of a feed on demand schedule/ stay with baby, a simple cheap manual or electric pump will work fine.
I assume that you will be delivering in the Holland area. Contact your hospital and find out if they have a Nursing consultant. Ask what she recommends. Go in (they usually have examples)and look at them.
I used a hand held electric pump when my 3rd was in the hospital and also a hospital pump sometimes. lol If you ever want to feel like a cow..... :-) And wow, louder than you would think they would be... Or maybe just more selfconcious... But most of the time with all 3 I just used a hand pump to take pressure off at night. Even doing that, I did end up with quite a bit of milk in the freezer.
You will not have to worry about pumping in the hospital... Your milk (as a first time mom) will probibly not come in fully until you are home.
Ask your hospital about what your insurance provides. We have BCBS and insurance pays for a manual pump AT THE HOSPITAL. Its brand new and you take it home with you. But usually you have to ask them for it.
NOTE: Any open packs of diapers, etc in the baby bed is YOURS. They also usually send home extra "tucs" pads and other supplies you use. Don't turn them down... And don't forget your "peri " bottle... You'll LOVE it!
Your insurance may cover part of the cost of a more expensive pump, but may stipulate that they be brand new.
Also look at consignment stores for kids and infants. They may have a few pumps...
Also... Some moms can pump and get seemingly gallons of milk at one time... Others can only get an ounce or two at best. Pumps are not a replacement for baby. They don't do as good of a job. Try a cheaper pump first, then if you still feel you need it, spend the extra money.
