"For the first 10 days it was pretty tough as a dad but now that we're past that [phase] it has been fantastic.
"He's an awesome little man and we're very lucky to have him," said Holloway as they drove to nearby Rockhampton last night to prepare for his next pro-am from Thursday.
The Mackay Open was reduced to 54 holes after inclement weather provided the preamble, as he started with a two-shot lead into the third round tied with other contenders nipping at his heels.
However, Holloway questioned their faith at the par-5 No 10 with an eagle to regain the lead.
He followed that with a birdie on either side of five consecutive pars to sign out at 16-under par.
The victory exorcised a decade-long trips of demons, including four years ago when 23-year club member Johnson shook him off in the last round.
This time Holloway went into the series with no pressure.
"I didn't have too many expectations so I didn't know how good, bad or otherwise I was going to be. If I was going to have a bad day and finish third ...

He hadn't put his game together but this weeks things had clicked on the foundation of patience.
On arriving in Rockhampton about 6pm (NZ time) yesterday, last year's Mondiale New Zealand Order of Merit winner saw ominous signs after the area received 150mm in the previous 48 hours.
"It's clouding over and looking like it'll rain. The river in the centre of the town is pretty full of water."
Holloway, who consults Hastings PGA professional Brian Doyle, of Hastings, will return home on Tuesday next week.
A gracious Johnson said on the PGA website: "It is great to see Doug win, as we are somewhat of the veterans still playing out here on the Sunshine Swing. I know it's a special time when you win in front of your family so I hope he enjoys that moment with Rebecca and Jack over the next few days."
The Sunshine Swing forms part of the PGA series comprising 200 events Australia wide.
