coming into this late. IDK where you are in AZ but I lived 35+ yrs (currently in PA for a time until we can get back to AZ).
Check the EPA site & "Superfund sites", US Geological, etc.... In Scottsdale, there is a serious superfund site, no thx to Motorola, as well in e. PHX & in Maryvale area there was a cluster of childhood cancers/leukemias.
Every state has these polluted areas - some worse that others.
Also, some areas in some states have old mines & landfill areas that have had housing developments built on/around them.
what you & Dad might've been indirectly exposed to could be a factor.
Our DS is totally unvaxed, breastfed to 26 mos, etc.... very little illness & he has some sensory issues. Why? PA has the hightest level of mercury in their soft coal in the east US.. There are little pockets of coal mining everywhere plus all these rust belt states have poluted land/water, abandoned mines, etc.
The west & sw US has/had lots of plants of electronic part production & the solvents used to bathe some of these parts were discharged into the groundwater systems (Scottsdale, AZ).
Also, when I was 1st pg w/ DS..... OMG, I CRAVED Long John Silver fish. IK, IK... but it was so good. That went on 4 mos.. I blame the PA pollution & coal fired energy plants dotted around the state. Even tho the closest 1 is 60 mi away, air moves. I did have 3 ultrasounds tho. b/c I was an over 40s mom & they found a issue with 1 of his kidneys in utero still has it but doesn't cuase him much issue. He was born emergency c b/c I had PIH & preeclampsia. My b/p was heart attack/stoke readings (bottom # was like 120) so he had to come out ASAP. I'm sure that didn't help but our lives were at stake.
(( HUGS)) for your family. I do feel very confident that DS had the poteential to be much much worse had we not done the above. He seems to be do a lot better that others AFA the symptoms going away & outgrowing his issues.
I will pm ya for some sites that may help... Don't beat yourself up.
You gave you DS the BEST possible start in life. Be proud of that.
I have a DD born in 1982 & the kids were much healthier then ( a lot less vaxes, etc) I really blame the pollution & the regs differ so from state to state. It's not only 1 Prez fault. This has been going on for decades.
DH & I grew up in the "petrochemicals are good for you" era
Gawd, we were exposed to everything, few vaxes tho, which think is to blame for high cancer rates, auto immune issues,etc.
You were informed, did everyone you could but some of our kids "seem" to be predisposed to some of this more so that others. just a theory of mine.
((( hugs ))) it will get better.
excuse the spelling errors, etc.
