Heat rash ?

I don't find this normal. I will bring to PD immediately if this really happens to my LO. My LO had rash a small red dot. Then slowly it grew bigger and bigger. One day she had fever and was hospitalized. She was 16 days old. The rash - doctor diagnose her with Neonatal lupus (pls google if u dont know. Its not a small illness). As a mother. I pay very close attention. So my advice is don't take things too lightly. If u don't feel assured. Bring to PD or hospital immediately to seek professional advice💓
