Breathable carriers for tiny babies

So I have an ergo baby carrier that needs the infant insert. My daughter is only about 7 pounds at almost a month old so she has to use the infant insert. However it makes her SO hot and sweaty even if she’s only in a onesie. However I would love to be able to baby wear to be able to get stuff done, especially since my husband goes back to work next week. So what are some good carriers that will work for a tiny baby like mine without using an adapter thing, that is also breathable and doesn’t matter what she’s wearing?
