Who's to blame?

There has been an ongoing debate in our house about the water we are mixing my son's formula with...we have been using the water from the tap, which as far as I'm concerned is just fine, but not in my lovely wife's opinion. I thought with the second kid we were done worrying about all that stuff, but apparently not. With our daughter it was nursery water and bottle warmers all the way, as well as sterilized pacifiers as soon as they even came near the floor. But with baby boy it's been a whole different story, pretty much just the five second rule in full effect. So that's why this whole water thing has caught me off guard, I mean he's now over five months old so why the big to do now? Apparently my wife read something about the dangers of lead levels in water, especially in rehabbed buildings where the builder neglected to replace old pipes, just like our condo. So next thing you know I'm at the Ace looking for do it yourself water quality tests, and I finally find a home kit that clearly states right on the package, Free lead in water test inside. So I pay the twelve bucks and head for home to test our water, already feeling confident that it will be safe. However once I get home and open up the kit I find every other test there is, and a card to send in for a free lead test, which says once receiving the test I can send it in with a thirty dollar money order or check to get the results. How lame is that? Talk about false advertising! Well I test the water for all the other things the kit actually came with, and discover our water quality is perfect, but I still don't know about the lead. At this point it's time for baby boy's next bottle, and I'm thinking just go with the tap water like we've been doing for five months. And lets not forget that we were all raised with tap water and turned out just fine...at least for the most part. So I give wifey a call at work to see what she thinks I should do, and she is pretty adamant about no more tap until the lead is tested, even after I tried my best to convince her that all the other tests came back safe which means there is probably no lead either, but she just wasn't having any of it. Next thing you know I'm busting out the nursery water and bottle warmer and fixing baby boy his bottle, but he was starting to fuss so I was doing all this while holding him. I get the bottle all heated up and ready and then while still holding baby boy I pick up the bottle warmer with my left hand and proceed to dump it out into the sink. Obviously forgetting that the bottle warmer uses super heated water and steam to heat aforementioned bottle therefore I burned the crap out of my finger, we're talking third degree here, the skin was basically dripping off. So the first thing I do after screaming and dumping baby boy down in his bouncy seat is to call my wife and yell at her for making me burn my finger off. I mean you tell me, who's to blame?
