The Picnic That Floated Away

The Picnic That Floated Away Ages 5–8 • Gentle read-aloud story • Friendship, feelings and problem-solving A warm children’s story about a breezy picnic, a runaway biscuit, and finding a happy ending when plans go a little sideways. Story Time Mia had been looking forward to the picnic since breakfast. She had helped Mum pack the sandwiches into a blue plastic box. She had chosen the biscuits with the little jammy hearts in the middle. She had even folded the napkins, though one of them had come out more like a crumpled cloud than a square. “Picnics don’t mind crumpled napkins,” Dad had said. “They’re very relaxed.” Now Mia was walking through Willow Park with her rucksack bumping gently against her back. Jack was skipping ahead with a football under one arm, and Ella was carrying a small soft rabbit called Clover, who had been invited to the picnic because...

Age 5–8 Read aloud: 8–10 minutes Theme: calm problem solving Story Time The bus stop was shining in the early evening rain. Not heavy rain. Not the sort that soaked your socks and made your sleeves drip. Just soft, misty rain that made the pavement sparkle under the streetlights and turned every passing car into a blur of red and white. Mia stood beside Mum with her hood up and Mr Buttons tucked under one arm. Mr Buttons was not a new teddy. He had one ear that flopped more than the other, a patch on his tummy, and three real buttons sewn down the front of his knitted waistcoat. Mia had slept with him since she was tiny. He knew about bad dreams, secret whispers, and the exact place on Mia’s pillow where teddies fitted best. A red double-decker bus came rumblin...
