Well the kids I know who are super vaxed (my SIL is a nurse and gives her kids every vax available including getting them into studies for new ones) are very ill behaved to say the least. Now part of it is just plain ol poor parenting. THose poor kiddos don't get any love and attention from their parents so they act out to try and get some sort of recognition from any adult around. My niece also has an eating disorder. She is almost 4 and eats uncontrolably. She will eat until she vomits and then start all over again. She just can't seem to stop herself. She steals food off of other peoples plates (which while normal at 2 is so not normal at her age) and will rip food out of other kid's hands if they won't give it to her. SIL swears she doesn't have a problem. My brother's son also has quite a few budding sensory issues and social problems. He is also hyper vaxd (his mother was also keen to get him every vax available as well as a few vax studies). Now sensory issues tend to run in our family, but I notice every time she takes him in for a new vax he gets worse. She just dragged him in to the Dr. and demanded he be vaxed for rotovirus (because it wasn't out when he was a baby). Naturally she then brought him aroudn my kids while he was shedding.
: And he has developed a new resistance to eating with his hands. He won't eat sandwiches because the bread will get his hands dirty. He doesn't really feed himself anymore at all, they spoonfeed him, he is almost 4 as well. I would not be suprised to see him become fully autistic after his next round of vaxes on his b-day. It makes me very sad, but my brother will not hear me out. He knows that we believe ds1 became autistic after his vaxes, but he doesn't believe it and won't hear anything about it.
My own son is now PDD NOS as a direct result of vaxes at 18 months. His baby brother is vax free and totally typical developmentally. My nieces from my other SIL who are selectively vaxed (late and with as few vaxes as possible) are also developmentally typical. Maybe it is just a family thing, but this is what we are seeing.
