Never having had a baby before i am not sure but think maybe my LO is teething. She's 13 weeks now and for the last week or so she has been dying to chomp on things. She's had a touch of nappy rash which she's never had before. She has a wee rash on one side of the face near her jaw and when I rub my finger on her gum I can feel 3 jagged bits at the back. I know it sounds like teething but isn't she a bit young? She is being really grouchy and isn't sleeping during the day now despite giving her calpol. If it is that does anyone know what I can give her? I know that the powders have lactose in and she's allergic to that.
