Molly examines her shelf of special things at the back of Mack’s stall. She chooses the homemade beard and remembers the day she got it.

James, Alice and Molly are exhausted because baby Maddy won’t sleep. They think they’ve tried everything, but Molly points out they haven’t tried Bob. Bob sings a lullaby, and it seems to work despite Moira nearly ruining things by using her loud vacuum cleaner nearby.

Meanwhile, Mack is helping at the Kids Club. Ruby, Euan and Ayesha decide to try to grow a beard. When that doesn’t work, they make their own beards. Mack makes one too and looks a bit like Bob.

At the cafe, everyone is enjoying the silence until Molly knocks a jug over and wakes Maddy up. Desperate to get her back to sleep, Molly convinces Alice and James to imitate Bob. They put on their best Bob voices and sing the lullaby, but to no avail. When Molly sees Mack walking past with his Bob beard, she has an idea.

Soon everyone has a Bob beard and sings to the baby, but Maddy keeps screaming. When Bob arrives back at the Hub, he has another go at singing, but nothing works. Molly finally realises that it wasn’t the singing or the beards that were making Maddy sleep, but something else at the Big Hub. Soon Maddy is sound asleep. Show less
