My 2DDs had this and I got some stuff from the States - Silver cure. Theirs went away very quickly when I used this.
I know it's not cheap ($59) but it is horrible when your LO have it. I would recommend the ointment, I did get a whole pack that had soap, shampoo and a spray but i think the ointment was the stuff that really made a difference. Also it's not harmful to the child, it's perfectly safe even for very little ones.
