My baby has had these bumps and that lil light patch for over a week now. She doesn't scratch it at all. What can they be, if anyone has experience this, please share.

Also she has some red bumps in the crease in the back of her neck that she continues to scratch. I think those may be heat rash. How can I get rid and stop the itching. She's so irritated by it.
