I agree with the sentiment of your post OP. I think it's awful how we, as a society, seem to be moving towards this value of everyone must work outside of the home and without seemingly any thought for child development.
A baby needs to be with its primary care giver for at least a year in order to form a healthy attachment, if this doesn't happen then that child may have difficulty with relationships for their entire life. There is a theory that ADHD may be linked with insecure attachment.
There's huge value in looking after babies and toddlers but as a society it's often viewed as drudge work and paid a pittance (if you work in a nursery).
I'm not saying there shouldn't be a choice, I know since I was a SAHP mortgages alone make it hard to afford to be one.
Parents should be able to make choices but we need to make informed choices and/or not just be pushed into it.
