We did it with our first because my dad has MS and thought there could be potential for him or on the off chance myself of the kids get it.
We chose based on a combination of price, and reputation. In the end, we came down to 2, one on the West coast and one in central Canada (we are Canadian). We ended up choosing based on location because my husband felt the chance for natural disasters was higher on the West Coast.
For my second, I was thinking of donating but when she came early, everything happened so fast nothing was done.
