I dont think its the synthetic fiber thing cause we use fitted nappies mainly during the day that dont have stay dry inners. Maybe an allergy? Carolyn suggested silk liners just to see and also cut back his dairy. My dad has a dairy intolerance and so does Carolyn's son so could it be that??? (as he reaches for his cup of milk

)
He is teething, well, all his teeth have just come up in the last week. I really doubt there is any more there, there is so many already
It is really annoying though, I have all these really nice night nappies that aren't getting the use they should
EDIT: I do try and change poo's asap cause this does make it much worse. Its such a horrible feeling when I didn't realise that he had and when I change him there is a surprise and a red bum to prove it
