Dairy allergy

Any tips on how to figure out if my daughter still has a dairy intolerance?

She’s ebf and we’ve been dairy free for almost 9 months and I’ve slowly tried to introduce dairy into our diets but I’ve always stopped because she has eczema.

But it seems that she always has eczema so I really don’t know if it’s due to the dairy.

I’d really like to give her yogurt and string cheese for snacks but I’m nervous.

Did anyone’s LO outgrow their allergy by this point?

If so, how did you know?

I’m totally fine keeping us dairy free but I’m just curious to see if she’s outgrown it yet.
