Our DD has been trying out solids more so within the last week & half. She has also been drooling a ton & putting everything she can get her hands on in her mouth. She is 9.5 mos. I've offered her strawberries within the last few days & yesterday I offered her plain yogurt (which she ate a few spoonfuls, this is a lot for her). Last night my DH & I noticed eczema type rash around the sides of her mouth, could this be from the yogurt or just from teething? I offered the yogurt again today & she only took one spoonful, then was uninterested. If DD is allergic to the strawberries or yogurt would a rash turn up within a couple of days or within a few hours? If it is within a few hours then I know it is the yogurt. Please advise.
