Ahhhh I see. You had less empathy before so you assume those around you without children have less empathy in the same way? A distinctly unempathetic view point really
It also relies on the assumption that everyone has the same levels of empathy in the first place....
Whenever I was struggling with fertility problems I actively avoided pregnant women and those with small children, I felt traumatised and angry and due to this I doubt I had much empathy
Avoiding situations that impact you due to your own personal circumstances is not a lack of empathy. Labelling people's behaviours that are about protecting their own personal health as unempathetic is very problematic.
my tolerance level and flexibility for dealing with children was absolutely stretched hugely from where it was prior to having children and I absolutely would have more empathy and ability to help a mother in need now than I would have had pre children.
But that's your tolerance and empathy. But as I have pointed out repeatedly some mothers abuse their children. When you refer to mothers as being more empathetic and tolerant than childless women, as two classes of people, you are effectively labelling childless women as less empathetic and tolerant than women who abuse their children.
And regardless of that 50% of teachers don't have children. Never mind childcare workers, nurses, midwives, speech therapists, child centre workers etc etc etc. There are millions of people who don't have children who are out there quietly helping mothers (and fathers) in need.
Whenever I had kids I also had some relatives and friends behave passive aggressively, or who lessened/stopped contact.
Maybe you made your feelings on childless people clear?
