About this episode

This episode explores how birth order and family roles affect sibling dynamics and child development.

Do you have more than one child? Are they constantly fighting for your time and energy? So how do you parent siblings? In today’s episode, I explore how birth order shapes your children’s development, behaviour, and long‑term identity. You’ll learn why research consistently shows firstborn advantages in earnings, IQ, and academic outcomes, and what sits beneath those patterns - from early illness exposure to diluted parental attention to the powerful “teaching effect” between siblings. I also help you unpack the hidden family roles your children adopt - the helper , the funny one , the responsible one - and how these labels quietly shape their confidence, conflict style, friendships, and even their future workplace behaviour. Most importantly, you will understand why each of your children is growing up in a completely different childhood, and how being aware of this helps you reduce friction, avoid unhelpful comparisons, and support healthier sibling relationships at home. With the tools and tips I share in this episode, you can start making meaningful changes today. So pour yourself a cuppa, find a comfy seat, and enjoy the conversation… Highlights from this episode: 02:00…
