Interesting and it makes me very sad for my daughter. I had hyper-emesis when expecting her, but one of the few things I craved was spinach, canned, which is high in iron. I ate a lot of it during the entire pregnancy. I also took the prenatal vitamins.
Of course it never entered my head that she could be low in iron....her pediatrician never mentioned it, and I can remember that she loved liver and onions (can you remember us eating those foods?). I had the exact same hyperemesis with her sister, ate a lot of canned spinach (always had to be canned for some reason), had the same vitamins (with iron) and while both were difficult births, lack of oxygen in both cases, the two were completely different in their personalities and schoolwork as the years passed. So I don't know how much worth I would give this.
Also, I provided both with nourishing food, the second was far pickier than the one with ADHD, and vitamins. I would have surmised that the second child would be in much worse condition than her sister. Of course then hyperemesis didn't exist either....the reasoning behind it: You actually didn't want the child! So wrong, but thinking changes even if it isn't in your time. Our second daughter was quite the opposite, very smart and didn't act out in the classroom. My first daughter was almost 9 lbs. at birth, so she was probably getting nutrition from me, such as I was able to provide in that time. I only gained 20 lbs. or just less. The second child was 7 lbs. 8 ozs.
I wouldn't wish those years upon anyone. This daughter is now 50 yrs. old and quite healthy. Yours, Lenora.
