What to Do W/feeding Pump?

What about putting it on craigs list or ebay?

They will know its used and it may help that one family who can't afford it. If you do a craigslist you wouldn't have to put the amount on it. Just put a general listing that its used and for sale. If someone is serious about buying it they can contact you for more info and then you can state if its free or what ever price you put on it.

I understand the hospital's view of the personal nature of its use... but someone who really needs it may look past that and see it as a blessing they couldn't afford... even with a rent to own.

First off, glad to hear your son is now healthy and that the pump helped him grow!

Since it can't be donated for human use...what about donating it to an animal hospital or a zoo for animals that need assistance following illness or surgery? As such, it would most likely be able to be used as a tax deduction going to the organization or facility?
