@springwillow This sounds like a post for r/noctor. That's a subreddit about mid-level practitioners working beyond their scope and giving false or dangerous information. Ideally, you should see an MD, not an NP, they are not qualified to be doing diagnoses and referrals like that, especially for peds. You can ask the doctors over on r/noctor or even on r/askdocs if you'd like, but sadly, NP's scope creep is getting out of control and leads to unnecessary worry or even dangerous neglect or wrong treatments. I would strongly, strongly advise you to do what you can to see an MD and not an NP.
Off the top of my head in my own experiences with seeing NP's practicing independently without supervision instead of MD's, I've: (1) had the wrong cream prescribed for a yeast infection, (2) has a skin issue incorrectly diagnosed as bug bites, whereas when I saw my MD PCP, he immediately, correctly, identified it as a form of eczema blisters that just appear on hands and feet and then was prescribed a cream that actually helped, and (3) was given antibiotics for something that, when I saw my MD, told me antibiotics are useless for and to stop taking.
These are all relatively low stakes things but it's part of why I would never see an NP for anything diagnostic, only for things like a medication refill.
So yes, please do double check with an MD, and check out those other two subreddits I mentioned.
Edit: this is a huge issue nationally in the US. I have relatives in the UK and go to NHS clinics sometimes when I'm over there, and never had to see an NP, and they seem positively shocked that that's becoming routine in the US, with our supposed "great health care." Unfortunately, a number of states keep passing legislation allowing NP's to have "independent practice," DeSantis in Florida just vetoed a bipartisan bill that would formally disallow NP's, PA's, etc , from calling themselves "doctors" in a health care setting, and corporate conglomerates keep buying up small practices and hiring only NP's with maybe one supervising MD instead of staffing with doctors.
This is because these health care conglomerates save money by hiring NPs instead of MDs but then bill us, the patient, and insurance, the same, making their shareholders more money. At the very least, if you're made to see an NP instead of an MD, check your insurance billing and if they're coded or charging the same per visit as with an MD, demand that it be corrected and changed to the lower insurance payout for a non-physician visit. We are only getting stuck with suboptimal primary care because nobody knows about this and it makes the cost-cutters more money. We need to fight back.
Second edit: I'm an attorney and know for a fact that this is a growing issue in the country, and more and more data is being collected on patient harm and cost due to corporate and legislative-pushed mid-level scope creep.
Third edit: a three year study from the American Medical Association that's being caused by NP's being the primary point of contact for patients. This is in an emergency room setting, but is just one of many such studies.
