Sensitive Skin

So I’ve taken my 11 month old daughter to the doctor 4 times now In the past few months for her skin. It started when she was about 3 months old. I mainly get told that it’s eczema which I believe because my mother and I have that and it looks and feels like it in some places. Other places though I get worried it’s a rash I need to take her in for. I’m tired of being told its just eczema when I take her in for a new rash. It just always looks so different I don’t want her to be showing a rash and actually be really sick and I don’t take her in. Here’s a list of the skin issues we’ve had.

-begins the knees, raw red, wet, flaky, itchy been there for months can’t kick it.

-small bumps on the top of her feet and wrists??? Weird one but they dismissed it.

-actual eczema patches on diaper line of her back and shoulders.

-sometimes she has a rash like today. It’s not dry and flaky it’s just red and a little warm and I’m just unsure.

Any help for a mama worrying about her babies skin?
