Prince William was given a onesie with "My daddy's hero" written on the front, as well as a "Help For Heroes" teddy bear while touring the Tedworth House Recovery Center with Prince Harry on Sunday, U.K.'s Mirror News reported.

With two months to go until the birth of the royal baby, the Prince William joked about sleepless nights ahead. When he spoke with Corporal Josh Boggi about the upcoming birth, Boggi asked, "Are you looking forward to it?" to which he replied, "Very much so."

Although Boggi offered the royal to hold his two-year-old son, Prince William said, "No, no, you're very kind."

Parents offered Prince William advice while he was at the center in Tidworth, Wiltshire.

"All the mothers have been looking at me, [saying] 'just you wait, just you wait. Long sleepless nights,'" he said.

Prince William, a RAF search and rescue pilot, completed his second tour of Afghanistan this year. He listened to injured soldiers and their families speak how the Recovery Center has changed their lives.

According to a recent report, Kate Middleton will be the first royal figure to announce the birth of her baby on Twitter when she gives birth mid-July.

While Prince Harry announced that the royal couple will have a boy, the soon-to-be parents have been careful to keep this information under wraps.

"Harry has been telling everyone Wills and Kate are having a boy and how thrilled he is at the prospect of having a little nephew," a source said. "They're really working hard on baby names and think they have it sorted but they won't reveal anything to anyone -- not even Harry."
