  1. Fold three or four sheets of paper in half and staple the fold to make a small book.
  2. Write on the cover: 'Tilly's Big Sister Book' (use your child's name).
  3. Open to page one. Ask: 'What's one thing you can do that the tiny one can't?'
  4. Whatever they say, write it at the top of the page in big letters — 'I can climb the stairs!'
  5. Give them a crayon and let them draw a picture underneath.
  6. Turn the page. Ask the same question. Write the next thing.
  7. Keep going until the book is full — five or six pages is plenty.
  8. Read the finished book together and put it on the shelf where they can reach it.

Parent tip

Set out crayons and paper before inviting your toddler in so the first minute feels smooth.

What success looks like

Back-and-forth between you — words, gestures, shared pretend. Connection is the real outcome here.

Take three or four sheets of paper folded in half, staple the spine, and call it your child's Big Brother Book or Big Sister Book. On each page, your child draws one thing they can do that the new little one can't — climb stairs, eat cucumber, give cuddles, sing the alphabet. The book becomes a physical object they can pull out on a hard day to remember who they are. Identity is the deepest source of resilience for a toddler facing displacement.

Why it helps

Zero to Three guidance on preparing for siblings emphasises that the older child needs reassurance about their ongoing role and importance — not just the new arrival's needs. NSPCC's Look Say Sing Play research highlights that strong, positive self-narratives in early childhood are protective against the dips in self-worth that come with major family transitions. A handmade book your child has authored is exactly the kind of identity scaffold that holds up when other things wobble.

Variations

  • Add a new page each week as your child learns new skills — the book grows with them.
  • Read it at bedtime on hard days as a quick identity reset.
  • If you have older siblings, let each one make their own promise book in parallel.

Safety tips

  • Don't suggest things for your child — let them generate the page content themselves.
  • Avoid comparing the book content directly to a future newborn's limits in a critical way.
  • Use round-tipped scissors and supervise the stapling.
