My 7 month old doesn't have a temp, eating and drinking normally and generally in a good mood, smiling, happy. But she has this redness on her forehead, it's smoothe, not raised at all.. it's almost like she's banged it but I don't think she has, it's appeared and disappeared over the past few days. Her red cheeks I think she could be teething but I don't see any new teeth popping through. Any ideas? It's not bothering her either. TIA
