As you know, we have been battling for a long time a rash on Lillian's bottom. We have been giving her a nightly zinc supplement for almost 2 weeks now and it seems to help. Actually, I am not really sure if it is the zinc or something else since she has been clear a little longer then she has been getting the zinc, either way, I will take it. However, she still has that rash on her abdomen, but I am thinking that has more to do with the cold and dry weather. we will have to get a cool mist humidifier for the house.
