It's the start of the summer holidays. Joy is six months pregnant - the twins are going to have a little brother! Mummy announces an after-school treat - a puppy training class with Grandma's new puppy, Pippa... yay!

After the class, the twins walk Pippa to a playground where Tony is swinging high on a swing. Dogs aren't allowed in the playground, so Topsy walks around the perimeter fence with Pippa on the lead to show her to Tony from there. Mr Welch calls to Tim to tell him not to play near Tony's moving swing. Tony stops swinging and Mummy and Grandma arrive. They ask where Pippa is. In the hullaballoo with the swing, Topsy got distracted and Pippa has gone!

The children look for Pippa from the top of the climbing frame, but can't see her anywhere. Tony mentions that, like Joy, his mum is pregnant and he'll be sharing a bedroom with his brother Jack. Then Grandma remembers how they were taught to call Pippa in class. The children climb down and one by one and then altogether they call, loud and jolly. Pippa reappears from a tree nearby. Phew!

Later, Dad gets home from work with an old, disassembled cot for the baby. Mummy and Dad explain that they will need Topsy and Tim to share a room again once their new brother comes, just like Tony and Jack.

As they move Tim's stuff into Topsy's bedroom, the twins ask if they will still be loved when the new baby comes. Mummy and Dad reassure Topsy and Tim that there is plenty of love to go round for all of their family and friends. Show less
