Mums, dads and grandparents joined their youngsters at Hallcroft Infant and Nursery School to fundraise for the Macmillan cancer charity.
Jo Cook, headteacher at the school, said: "We had lots of fun eating cake and raising money for Macmillan.
"Each class, Acorns, Oak, Willow and Rowan had an individual 'coffee session' when the children sang songs ranging from I’m a little Teapot to Colours of the Rainbow.
"They then sat with their grown-ups and ate the cakes."
Cakes for the special event were donated by families, and over £100 was raised for Macmillan.
The headteacher added: "This is an annual tradition which was started at the school in 2013, and is a great event for parents and carers to meet each other and enjoy watching the children singing."
Donations from thousands of Macmillan coffee mornings across the UK help to raise vital funds to support almost 3.5 million people in the UK living with cancer, from the moment they are diagnosed, through their treatment and beyond.
