The Duke of Cambridge and his brother, Prince Harry, visited the Tedworth House in Wiltshire, one of four care centers for wounded soldiers backed by their charity Help for Heroes, on Monday.

While there, the Duke answered questions about becoming a first-time father this July.

Triple amputee Josh Boggi, 26, asked him “Are you looking forward to it Sir?” The Telegraph reports, to which he replied “Very much so. But all the mothers have been looking at me [saying] 'Just you wait, just you wait. Long sleepless nights.'"

He then offered for the Duke, 30, to hold his 2 year old son and he politely said no. "No, no, you''re very kind," he said.

At the event, the Duke spoke about the importance of helping charities that aid wounded soldiers. “We must not let the wounded men and women of our Armed Forces down. This official opening is therefore, I hope, as much a renewed pledge by all of us to go on supporting those who have sacrificed so much as it is a celebration of an amazing achievement,” he said, Daily Mail reports.

Meanwhile, Prince Harry has just returned from a trip to the United States.
