Walking in the local park, Bella and Mali learn about how rings in the trunk show the age of a tree. Bella is then curious about the apple tree on the estate. How old is their apple tree? With the help of their oldest and wisest neighbours, who have wonderful tales to tell, they try to solve the mystery of the old apple tree.

Bella is desperate to have a baby sister, or brother, just like Mali. News that Sam might be getting a foster brother or sister encourages Bella to ask even more questions about families and especially babies. The new arrival at Sam's flat causes a great deal of excitement, but Bella has not been listening to her parents and has made an incorrect assumption.

Sam is upset at all the chores she has to do at home, while David doesn't have to do any. Helping her dad fix a shelf and watering the plants makes Sam late joining Bella and Mali who are busy making dreamcatchers. When Sam's dreamcatcher breaks she blames David, and gradually Sam's feelings about David's arrival start to surface. Many hands make light work and there are plenty of friends around to help Sam understand that life with David will settle into a routine.
