Itchy baby!

Rina 🧜‍♀️

Help! My LO isn't sleeping she's so itchy! I've been to see a pedi several times now they just keep saying to put cream on her. I've now tried 2 different ones and both gave her a horrible rash so we went back to the Aveeno lotion... She's scratching open her neck now so I've got mittens on her, but they are just constantly soaked because she chews on them... any advice??
