I gave my ds 2.5, grapes this afternoon for the first time in quite a long time, he's never had any problem with them in the past but I didn't get to his full nappy immediately (we were at the park so poor lad was in it for 45 mins maybe before I noticed. By the time I got him to bed this evening his bottom and front parts were so sore, he had sores all over his cheeks, it was awful, has anyone experienced a simular reaction with their child?
