Could you lack any more empathy?
Wow.
Sometimes people desperately want and plan their pregnancies and things are different than they expected due to SEN, disabilities (physical and mental), post partum, relationship or work breakdowns etc etc.
Comments like this are why mothers are terrified to ask for advice and help.
If we all judged a bit less then I guarantee it would help prevent so many of the mental health problems that mothers face alone. A lot of women won't tell anyone they are struggling until it is too late.
You are blessed and privileged to not only be able to make the choices you did, but to enjoy motherhood so much. I am genuinely pleased for you. Not everyone can be self employed and criticising women who put their children in nursery is not okay.
Women being expected to "put their children first" by stopping work or going into low paid casual work/unstable work are often left in financially abusive situations or on the breadline.
This is why men advance in their careers and employers penalise women. Your views are the kind that contribute to mum guilt and misogynistic attitudes towards women who NEED to work.
Clearly your lack of struggle and privilege of choice has left you with an inability to show fellow women compassion and an inability to see how those views affect women in a broader sense.
