Dry, peeling baby skin 😔

Carolina

So my baby has had skin issues pretty much since birth. It started with a bad heat rash and now it looks like eczema. She turns 4 months on Monday. She has flare ups but over the past 3 days she’s developed he worst flare up yet. Monday she got dry patches, Tuesday they turned red and today the skin started peeling and oozing clear liquid after her bath. I’ve tried cetaphil, eucerin, aveeno and baby dove products before but nothing helps (wash and lotions/creams). I’m gonna take her back to the doctor in the morning but 8:30 seems so far away, it’s barely midnight where I live. I’m scared to even touch her skin since it’s peeling where she has her dry patches. Do any of you mama’s recommend anything I haven’t Already mentioned? I gave her an oatmeal bath that made the swelling go down a bit but her skin is still peeling. She’s sleeping now but when she wakes up she cries so much I can tell it’s hurting her. :/ The picture is her skin yesterday with lotion on.
