My 2.5 yo DD has, I am pretty sure, ringworm in her nappy area (definitely not thrush). It is a small red circle which looks sore and DD says it itches and hurts. Made GP apt for next week but after speaking to the HV she is now going today.
Is this common? Is it ridiculously contagious? what should I be doing to look out for more on DD and other DCs (I have 4 month old DTs) and to minimise it spreading? I know I am seeing GP later but getting myself in a tiz about us all getting covered in it and DDs nursery having to close for a deep clean because of us 
Any words of wisdom gratefully received
