Adam, who plays Adam Barton in Emmerdale, shared a super cute father and son moment of him and Teddy a "boys weekend" in the Lake District.
Captioning the snap, he said: "Top weekend climbing with this lil guy!! What a day!!!|"
Actor Adam and long-term girlfriend Caroline Daly welcomed Teddy in September 2014.
Speaking to Adam at last year's Inside Soap Awards, he told Reveal: "Fatherhood is amazing. I love it. It's just the best thing. I want so much more!"
Adam, who is also known for his breakthrough role as school boy Donte Charles in Waterloo Road, said he had no plans to leave the ITV soap.
"I'm very thankful to be working here today with Emmerdale," he told us at the time. "It's the best soap on television entertaining the nation. It's brilliant, it's got no fault.
"I've been at Emmerdale for like six years now. I'm happy here and I'm loving it. Plus, I've got a kid to support now."
