Dry skin

Any suggestions? 4 month old with super super dry skin- flaky, peeling, and cracking in some places. We have a dr appt on Tuesday but until then what can we do?

We are smothering aquaphor on her about every 2 hours. This morning Iv started soaking wash clothes in breastmilk and wrapping them around her arms and legs for about 5 min. She only baths 2Xs a week. Desperate here to help find some relief. It’s so dry she scratches herself until she bleeds. Thanks in advance.
