Robin Johnson, 61, couldn’t help but let out the loud shriek the moment she discovered her daughter-in-law was pregnant.

“Robin responds like that when she’s surprised, although that one was bigger,” her husband and grandfather-to-be Bruce Johnson, 53, told InsideEdition.com.

The New York state couple was visiting their son Rob Johnson, 31, and daughter-in-law Keli Johnson, 29, for the weekend in North Carolina when they noticed a “Baby on Board” sign taped to the guest room’s door, according to footage licensed by Caters News.

They then opened the door, luggage in hand, to reveal a room decorated in balloons and the word “Baby” hung across the headboard.

“We’ve been looking forward to becoming grandparents for a while,” Bruce said.

He said he and his wife have been planning a trip to visit, and Keli, who is 17 weeks along, found out she was expecting shortly after. “They kept the secret through the entire vacation planning,” Bruce explained.

The expecting couple was even able to organize a gender reveal later that weekend, and even father-to-be Rob was shocked to see blue smoke, revealing a son was on the way.

“Rob had hoped for a boy, and while it’s great to have the family name carried on, we had no preference,” Bruce said. “A first grandchild is awesome – boy or girl. We can’t wait to meet him.”
