I don't know. I do wonder about all this. My children both have autism. Ds1 has terrible bowel trouble. Still soils himself at times and he's 11.
They never had the mmr.
If they had, no doubt I would be saying it was the reason. ds1 was clearly autistic from birth but ds2 'regressed' at the exact time that you normally give children the mmr - if I had let him have it, he would have regressed and I would have insisted it was related to the mmr. He was perfectly 'normal', interactive, good eye contact, loving and giggly and wanting attention in a way ds1 never did. Then the boy I knew disappeared. How would I think it was anything other than the mmr if he had had it?
But it can't be The Reason or why do my children have autism when they never had the mmr?
If it is a trigger, why does it trigger in some and why do some who don't have it turn out exactly the same way? Does that mean that some would have autism and bowel problems whether they had the mmr or not, and that some only had it because they had the mmr and how do you tell who would have had it without the mmr anyway? There's just so much uncertainty.
I agree it's about wanting to know why! I can't say it's the mmr because it's not, in their case. I think it must be genetic, in their case.
Or maybe those jabs they have at a few weeks - what's it called? Used to have mercury in it? Or perhaps it's all the additives and preservatives in food, or pollution...
It's the not knowing that is worse, not having a 100% unarguable, proven reason.
I used to think I'd done it by being a bad mother and if I'd been a better mother they wouldn't have autism. I blamed myself for years.
I also wondered if I'd done it by feeding them baby food from those jars.
