I am majorly rundown (the juggle of two in nappies is getting the better of me - advice on holding up to the physical pressure, please!) - have recently had 5 feverblisters/cold sores at once and then got a majorly bad mouth ulser on the gum and now my tongue is swollen, with sore little white spots - one on the tip and the other on the side. I think my almost 3 month old may have oral thrush. Any treatment ideas for this?
