dd2 is MSPI, and ebf, so I've been dairy/soy free since April. I just noticed this morning that my allergy meds (zyrtec) contains lactose. Now I know lactose isn't the same thing as casein, the milk protein, but is it going to cause a problem for dd2? I've been taking it because zyrtec is safe for bfing, and earlier, I had a really bad case of hives and my dr wasn't sure if it was fungal or allergy-related, so I started taking zyrtec. dd2 still does have occasional mucousy poops, but her eating is better, her reflux is controlled on meds, and there isn't any blood in her stool. Should I cut out the zyrtec because of the lactose?
