Going back a bit here but Chelsea Fagan of The Financial Diet is vocally child-free - her channel is a financial advice channel aimed at women broadly. Lots of the specifics of the advice are US centric but she is a great interviewer and very no-nonsense.Speaking of influencers, I can’t actually think of any female influencers mid to late 30s that are actively and vocally not interested in having children. Can anyone remind me of anyone?
