I sympathize very much with the baby, and the mother as well. It would be difficult for me, as a mother, to do that experiment. Although I was watching the video objectively, understanding that it was an experiment, my eyes welled up with tears as soon as the baby began to cry.
I have two boys, one is diagnosed with AS and the other is not. As far as I remember, both of them acted similarly to this baby.
I had thought for a while that I might be mildly AS myself, but I've decided I'm not. If I'm going through a major depression (which I have done often for huge chunks of my life) then I have a lot of disabling AS traits, sensory problems, and social difficulties, but they seem to all but disappear when I'm not depressed. I think in general, any AS traits I have are mild enough that I can't claim the AS label, so I suppose I'm speaking mostly as a non-AS person, more or less.
It's interesting that this video makes you angry at the baby. The baby is probably only about 4 or 5 months old, so that's not manipulating any more that it would be "manipulating" if she reached out and tugged at her mother shirt when hungry. It seems to me that a baby this age needs its mother to pay attention to it for survival as well as for cognitive growth. Do you think perhaps your anger is actually envy? (I hope that doesn't sound offensive or presumptuous. I really don't mean it to. I'm just thinking of possibilities and wondering, out of curiosity.)
