The parents of two-year-old Jamie Heaton, who died in an explosion in Shaw, Greater Manchester, paid tribute to their son, saying: "Jamie was unique and amazing. We will miss everything about him."
Michelle and Ken Heaton released their statement after visiting the scene to see the messages and flowers left by well-wishers.
They also thanked the local community for the "tremendous support" in the wake of the tragedy.
Jamie was killed and neighbour Andrew Partington, 27, suffered serious burns as Tuesday's blast flattened their homes and damaged scores of other houses.
He died while watching TV in his home but his mother miraculously survived after stepping out to hang out washing in the yard.
Michelle and Kenny Heaton hugged each other next to a makeshift shrine of flowers from well-wishers as a statement was read on their behalf.
"Our little man Jamie was a happy little boy, mischievous and full of laughter.
"He loved watching Mr Tumble and Peppa Pig, he was in his element in the outdoors, he loved his freedom, going to the park, playing on the slide.
"He adored his family, his brother and sister Jack and Jodie, they loved their cuddles and play fighting.
"His personality was unique and amazing. Jamie was unique and amazing, we will miss everything about him even though we only had a short time with Jamie, the time we had was special and his memory will live on through Jack and Jodie and everyone close to him."
