Aylesbury MP David Lidington got down with the kids when he visited Little Acorns Nursery in Wendover.
Staff at the nursery invited the Minister for Europe to visit the site, opposite the John Colet School, after they approached him to enquire about the possibility of more funding for nurseries across the county.
Nursery manager Michelle Russell said: “We were delighted that David accepted our invitation to come and visit us and see what we do here.
“He was very hands on with the children and happy to join in the activities.
“The children had been making Chinese dragons and he was playing with them.
“He was sat on the floor in his suit and the children were almost mobbing him at times!
“It was just great to see him getting so involved.”
Mr Lidington visited the pre-school on Friday.
