what about trying goat's milk? We've not introduced any dairy into dd2 yet (too scared, and she's still little). But at 6 mos, I started eating goat cheese, and she's done fabulous on it. The protein is easier to break down than the cow's milk protein, so it might be a good start. I have no idea what I'll do when dd2 is a year and starts dropping milk feeds, I don't want to (and can't afford to) switch to the crazy expensive formula, but I"m scared to go to cow's milk. Liz also recommended oat milk to me too.
