I think that we set many children up to fail, or feel like failures, if we don't let them know that 'having it all' is rare and that the whole spectrum from career focused and no children through to SAHP (if you can afford it) are valid outcomes.
Having choice is empowering, attempting to live up to an ideal instilled in your formative years can be devastating. Knowing that £6k per term was spent on your education can create pressure too.
Something I think is missing from the debate is that we often think of how people balance family life with small children but not older ones. So nannies, nursery, CMs, 7pm bedtime then back online to work, vomiting toddlers. In many ways, teenagers need their own parents more. A teenager is less likely to accept a nanny, they stay up later, have more complex issues to deal with. Having a family/work balance isn't about getting through the first 5 years. It is 18 years as a minimum. That isn't a few years off the career path and jump back on, it's getting on for half your working life.
