Hello, I read from one gynecologist that excessive folic acid intake can cause autism while pregnant. My tests showed higher than normal levels 2-3 times. Since then, I haven't found my place. The baby is 7 months old already. I constantly look for inconsistencies. I have gone through all the internet. They say overdoses don't happen. Excess is excreted in urine. Can you tell me if this could be true? Sometimes your child responds sometimes not at all. When did your child respond? Maybe it's still early? Every day I think about this, my head will explode ?
