Have i passed on herpes to baby?

[worry_wart83]

Ive been noticing symptoms of herpes on my buttocks for about 5 weeks (Details of my symptoms are listed in the herpes community forum under same user name with the heading 'red pimple like dots on buttocks') and now Im freaking that if I do have herpes I couldve passed it on to the children Im looking after. They are both in nappies so of course Im changing them all day. They both have a bad cold and have had tempertures etc. Ive noticed the youngest one has little red dots, almost like blisters around his testicals and in the creases around there. He is teething really bad aswell so he has really bad soiled nappies which does cause his bottom to be really sore and often breaks the skin but Im just freaking that this time its herpes!!! I know Im prob over reacting but what if it is?? They are not my children what will happen if it is? Im making myself sick over this that i couldve passed it on. Please help me!!!!
I guess my question is what are the chances of me passing it on if i have touched the area on me where i think im having an herpes outbreak then forgot to wash my hands and then changed their nappy....?
