And did you ever cheat or have a mess up?

I've been doing the MSPI diet for 2 months. It basically sucks for my social life and I have no clue what I'll do over the Holidays as we'll be traveling to Canada and then down to Virginia to see both sides of our families and having lots of family events with food cooked by other people, plus lots of time on the road (we are driving....yes, driving with a 5 month old....4 legs of an 8-10 hour car ride over a period of 2 weeks). I'll be staying with family on both sides of the family and there are many planned events/parties on both sides that we will be attending, that aren't potluck, and therefore I won't have much control over the food.

I don't anticipate a lot of time for me to grocery shop and frankly, after missing out on good Thanksgiving food, I WANT to be able to eat some of my holiday favorites.

So.....I have a good amount of frozen MSPI bm (a couple hundred ounces). I know diary can take 1-2 weeks to get out of the system, but does anyone know how long soy takes to leave the system? I'm considering giving LO frozen milk, avoiding dairy, but eating soy (I'm fine staying away from dairy, but most people use vegetable oil in their cooking and I'd like to be able to eat at least some of the things that are served). I've read 4 days online, but I don't know if that's true.

So, have any other MSPI mamas done this? (fed frozen BM to cheat?)

I'm planning to transition to elemental formula when LO is 6 months so we are AWFULLY close to my goal. My husband says I should just eat whatever and give LO formula if we have to. I'd rather give her BM to our goal (6 months will be January 12).

WWYD?
