I've got a 10 week old and she is allergic to milk protein. I've been on a dairy free diet for about 4 weeks now and she is so much happier. There are lots of foods you can eat. for breads go for french or italian breads, they are dairy free. Check all ingredients and avoid anything with milk, whey and casien. (whey and casien are milk proteins). I'm using rice milk when I need to add milk to something. for breakfast I'm usually eating oatmeal or bagels (no dairy!) I put either a vegan butter or peanut butter on it. Pretty much all asian food is dairy free too. You'll have to spend more time at the grocery at first but places like whole foods and possibily trader joes has a list of all their non-dairy foods at their customer service desk. just ask for it.
there are treats too. Newman O's mint are dairy free and very tastey and guess what is dairy free....pop tarts! I love pop tarts. :)
My best advice is not to let yourself get too hungry and make sure you have good things you are able to eat stocked in the house.
Good luck! I won't lie...i'm looking forward to being done with this diet but it's not horrible. i miss my mocha's with real milk.
