THanks everyone for all your replies. I think i will go to the Dr tomorrow just to be sure as if i dont go then and it doesnt clear up after that i wont be able to get there till staurday.

Marcellus - his nappies are wet so i'm sure he is passing his urine ok.

Kim - oh no, my sister got herpes when she was little too - still unsure how hope it clears for your ds soon too

Curly - i thought abut putting cream on it but i didnt want to irritate it further and since it wasnt bothering him i didnt want to upset him incase it stung - glad to know it doesnt though

Trillian - salty bath sounds good, thanks, i'll put him in one in the morning

Megan - hope your ds's clears up soon too. It could be a scratch. I use cloth so no stingy wipes here

Krysalyss and Sterla - its not really bad, but it is noticable iykwim? i hope its only something minor and wil clear up on it own.

Thanks again ladies for your help, its much appreciated. I hope in the morning its cleared but if not, its a trip to the Dr for us.
