I know you are afraid for your child. I understand.
But I honestly believe that your son will be fine.
Think about how many moms have cold sores! And children with herpes are getting more and more uncommon. The worst thing that could happen is that he might get cold sores also, right? He’s old enough to be able to withstand a herpes infection now. He’s not going to die from herpes.
I’m glad you are going back on your medicine and will have some greater sense of control over what is going on here. I’m not clear that anyone can put themselves in your place but I do have a sense of your anxiety.
Let me know if you have any other questions.
