For everyone who is sick or had accidents or have injured kids - wishing you lots of healing vibes and healthy times!!
As for the emergency section post mortum, I would probably trust DH to do that only because he was a med school drop out and had witnessed many surgeries - though I would never in a million years expect him to be able to perform such a feat. As for training, it starts with observation, then discussion and then scalpel in hand. Med students usually practice on cadavers first so they have a little bit of experience with the knife once they get into the operating room. Surgeons have a much longer and involved residency than most medical specialties because of the intensity of the job.
heathenmom, I am in a similar situation with the carseats - we really can't afford a minivan right now and I am trying to figure out how to get 3 across in our Rav4. We have FF DS who is in a convertible, RF DD who is also in a convertible (but will probably put her FF in the fall) and then the newborn. We have Britax seats right now and have looked into the Radians, but they are sooooo expensive... we may end up asking MIL for a loan to get a minivan. If we sell the Rav4 and have an extra couple of thousand bucks, we could get something decent.
As for me, if I don't get some sleep soon I am going to completely flip out. Seriously.
