MP John Hayes acted as milk monitor for the day in Moulton Chapel Primary School in celebration of World School Milk Day.
To mark the event, the school encouraged children to drink milk and understand the nutritional benefits it provides.
The annual event has been celebrated by children drinking milk in schools and early years settings in over 30 countries around the world since 2000.
In the UK, 1.5 million children under the age of five receive free milk every day, while pupils aged five to eleven receive subsidised milk.
