I'd replace the paper with something washable, but don't panic about
bacteria. If anything, I'd fear using anti-bacteria soap as it kills the
good with the bad and breaks down the body's ability to deal with it.

imho, this is exactly the problem. people try to 'sterilize' their home
environment but the world just isnt all that clean. i suspect that a baby
that was kept germ free for the first 3 years of life would have a tough
time if suddenly put out in the real world. that one commercial for the
sanitary wipes with the lady following her kids around wiping everything
just makes me cringe. pure scare tactic marketing.

i think it may be better to just let them roll around in germs and toughen
up. this is all purely my opinion....
