My One And A Half Year Old Daughter Has Recently

My one and a half year old daughter has recently started to get red bumps that are raised up, with white heads on them. They don't seem to bother her at all really. Doesn't scratch at them and it doesn't seem like they have been causing her any pain or been uncomfortable for her in any way. She has been getting them for a while and it seems like once the ones she has go away, suddenly a bunch more appear. This has been going on for about two weeks, maybe even three weeks. They are all over her body so it's not limited to one spot or only appearing on one specific body part. I really don't know what it is or what it even could be and its worrying me. I've made a doctors appointment for her to be seen but she can't be seen for almost another week.
