Great thread! I'm guilty of a lot of the same stuff others have said. Last night, my son had fruit loops (the Trader Joe's kind, but still) and cream cheese for dinner. It was one of those days. He also watches Yo Gabba Gabba or Curious George on a laptop whenever we go out in the car. It's the only way to prevent screaming, and better than lollipops every day, which is what we were using for awhile. We used cloth, but now DS is in sposies at night (it's only one a day, I tell myself!) And I totally bleached his cloth diapies more than once. We also have a ton of crappy plastic toys in the house. Before DS was born, I never would have expected I'd be the kind of parent that let my kid watch TV, eat sugary cereal and lollipops, or play with anything that once came from a Happy Meal, but I really didn't know what I was in for! :)
I learned early on in this parenting journey that I could either run myself ragged trying to do everything "right," or loosen up on a lot of my principles. I still have pretty high (and crunchy!) aspirations, but that's what they are most of the time--just aspirations and goals to work towards.
Oh, and I also have an addiction to Diet Coke that I'm not proud of, although I only indulge once a week or so these days. I've actually been known to hide our recycling bins when our uber-crunchy friends come over so they don't see the collection of Diet Coke and Red Bull (DH's addiction) cans. Blush.
