Don't slaughter me for this... This is only my opinion but ...
I had my first child last year and am on mat leave. I have Asperger's and have struggled with social skills my whole life, genuinely made my childhood miserable... Was bullied for years, never learnt how to make friends etc. I've made a real effort to attend groups and such which has been really difficult for me and is massively out of my comfort zone however I am absolutely desperate for my child to not have the same difficulties that I had. And now I am terrified that my child is going to be so anxious and scared when I have to put him in child care.
My understanding of the petition, and I agree the wording of the reasons behind it is woefully poor, is that new parents are genuinely, rightly or wrongly, scared that their children will struggle.
Even if people disagree with the OP and the petition, some kinder responses would have been more appropriate.
