Psoriasis

Does anyone’s littles have psoriasis? We’re thinking my little girl may have it as it runs in her dad’s family and she has some really red patches that have popped up that look like it. People said eczema but it looks more like psoriasis. She went to the doctor and they told me creams to use and to moisturize a lot if it’s eczema but nothing has worked. They said if it doesn’t seem to be getting better to come back of course but she’s only 4.5 months old😢 I feel so bad because it looks painful. She has it under her chin and then some patches on her forearm. I’m not sure if it’s a severe case of eczema or psoriasis. What age did it pop up for your little ones if they have it? I’m going to be making her another appointment for it of course.
