I have a few comments-I'm new and relatively inexperienced with this, but I thought I would put in my 2 cents!
First-Before I started MF, I had pm'd a few folks from another forum I am involved with, where there at least FIVE folks (that I know of) who have done or are doing MF. The only negative I got back was that one girl said it was too hard on the weekends to try to find ways to mix meals and carry water, etc.. So, I started out with the mindset that I would make sure there was a way!
That being said, I have an 8 month old baby who goes everywhere I go. I always pack a regular diaper bag, as well as her "food bag" with a bib, spoon bowl and baby food (I make most of it, so it is in ice cubes that I mix together in one of her bowls) and any necessary bottles, etc... So, I decided I can behave the same way when I am away from home. I have a small thermos (enough for 12-16 oz) of water and I always carry a water bottle wherever I go. So, that helps a ton. Last weekend, My family and I were going to go for a drive and I made the cookies out of the oatmeal and tossed them in a ziploc-how great that works out! The bars are a definite bonus, as well.
Despite this "preparedness", I went for a "quick trip" to wal-mart yesterday to get my daughter's their easter dresses-it turned into a long event and I ended up eating AN hour late once I got home. So, I did the best I could- I bought a jar of pickles and ate two on the way home!
This thread has all kinds of good information. It encourages me to order some ready to drink shakes in the future, just to have on hand. I love a challenge and this "travel thing" is a fun sort of challenge!
