The 27-year-old scored both in the 2-0 victory against the Bluebirds on Saturday, taking him to 11 in the Premier League this season.
"Reaching 10 in the league is fantastic, another little milestone for myself," said Wood.
"Having two strikers around the double figures mark is fantastic for the club. It's put us in a good position.
"It's nice that we keep ticking over together and keep scoring goals.
"They were both three yards out on Saturday, which is nice. It's nice getting those tap ins.
"Cardiff came and basically needed to win. They didn't want to get opened up too early.
"So it was good for us to get the early goal, we could have had a few more by half time but that's the way it goes."
