CPS for not taking child to the doctor?

My son has a sore throat with a cough, I know it because I do too, he doesn’t have a fever, and if anything you’d have no idea he was sick if he didn’t occasionally cough. He eats and drinks normally, he’s breathing normally, and he’s running around destroying my house like normal. My mom and mainly my grandma are insanely overbearing. They’re clingy to my son, they have to know what he’s doing everyday, constantly want to take him all day or ask if he can spend the night (I don’t allow spending the night because I’m just anxious about that, and he’s only 2 so I feel like it’s too early.) They absolutely will not get off my back that he needs to be taken to the hospital. I think he’s fine, I’ve given him the medicine he’s needed and he’s acting normal, hasn’t gotten worse and I feel like he’s gotten better, it’s only been 2-3 days.

Yesterday we were supposed to go swimming, I went to my grandmas to pick up my brother and my mom was there, they both ganged up on me and said my son needed to stay at the house because he’d get sunburnt, my SO agreed because he hates our son being around big bodies of water, I honestly didn’t care about him staying because I had friends coming and sometimes you need to socialize and have a break from constantly watching your kids every step. So I was fine with all that. I get back, and they both get back on my ass about how I need to take my son to the hospital, now he apparently has blisters in his throat, my mom saw it when she looked in his mouth. I don’t see anything in his throat, it’s not even red. (She did the same thing before swearing he had thrush, it was formula in his mouth.) All I hear from them is that he’s gonna die in his sleep or something from being sick, he’s so deathly ill looking. (He looks completely normal.)

My grandma and my mom both have a history of being CPS callers, even on family (my grandmas called on my mom and a few of my aunts before) for the stupidest reasons. Most of them just being stuff they looked for after the parent pissed them off. They’re petty and toxic, sadly I do have to be around them because of my younger brothers. If I had it my way I’d move far far away.

I was just wondering if me not taking my son to the doctors is enough for CPS to even be concerned.
