[|Human|] my 20 month old has a red rash from her ankles to, and including her butt, almost looks like bad sun burn, but is raised like a welt. It is starting to spread to her hips and small areas on her upper arm. She hasn t eaten anything abnormal and we haven t changed detergents.
[|AI|]  Hello, This might be Urticaria (hypersensitivity reaction)?  Maybe contact Dermatitis / Atomic Dermatitis! I just hope that there is No cold /fever! Please just don't get panic. If the baby is fine: no crying / Itching then just wait and watch. If its itching /painful/excessive crying then you need to give medication like Antihistamines.  Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
