Thanks for the advise - currently giving DS Panadol/Nurophen/Dimetapp combination for teething and/or a cold he is dealing with so will hold off on the dry pailing and just do a soak of water and tea tree oil.
I haven't been using bellybelly forums for ages lately but I think I will need to come back in occassionally - especially if I'm going to use cloth nappies more often.
