Well, I do a few of those mentionned above...
I make 24 hours worth of bottles and keep them in the fridge. Done it from the beginning, actually. Simon is fine and never had any colic or pains.
I also didn't sterilize everything every day. When using something new I did for sure, but then sterilized bottles and things once a week and then less often as he was growing up. He's never seemed to suffer from it. With a cat and dog in the house, he's bound to get more germs from them, I'm sure.
I stopped boiling his water for formula around 6 months old. I recently heard you had to always boil water for formula... Wonder why I never knew this...
I recently have begun microwaving a bottle once in a while if I feel lazy or in a hurry for his feeding.
We've napped together in bed a few mornings after OH brought him to me before going to work. It's not my fault if he falls back asleep!
But today I broke a big one: Simon had his first taste of soft-serve vanilla ice-cream! We should wait 'til 12 months, but he's 8 1/2... OH and I we're having some and he was actually drooling watching us. He was too cute! He only had about 1/2 teaspoon, but I still felt like I was going against the oh! so mighty rules to motherhood! I could actually see that chart on my fridge where ice-cream comes at a year old...
But hey, he's loved and well taken care of... except for those few little details!
