DD1 went to bed last night but reappeared a few mins later to say that she had a sore patch just below her bottom lip. When I looked there was a small (0.5cm) white welt type thing. She said it was really stinging. It didn't look like anything I've seen before other than perhaps a bite of some sort. I put a bit of aloe vera gel on it to try and calm the stinging. She also said it felt moist to the touch (before the gel went on!). Anyway, she went back to bed but when she woke this morning the patch had developed into a scab. She says it no longer hurts, but I'm just wondering what the hell it is?
Anyone any ideas?
