She's definitely lactose intolerant to an extent because I had to put her on soy formula at 2 months. My mistake was listening to my mom and trying to mix in regular whole milk instead of soy milk to begin with. *sigh*
But even after switching to soy milk and then back to straight formula, she hasn't improved. It's terrible!!
Here's a soy yogurt.

As a matter of fact, it reminded me that I had a whole sack of little Brown Cow yogurts...the boys are eating chocolate and I'm eating creamy coffee!
