Robertson, 32, admits that he wishes he had done the same four years ago after the birth of his son Alexander.
"It is a busy time of the year, with a lot of big tournaments," Robertson told Inside Snooker. "So I can see that Mark might manage his schedule with the European Tour to miss a few and make sure he spends some time at home with his family, and I completely understand that.
"It is something I wish I had done a bit more in 2010, but I had won the world title for the first time and I did feel a responsibility to represent my sport and play in most events once I got back from a summer back home.
"To be honest it did get pretty tough and my performances if anything started to get worse, so I'd have been better taking more PTC events off and spending some more time at home in between the big events."
Selby has already clinched his place in next year's PTC Finals by winning the first European Tour event in Latvia with a 4-3 win over Mark Allen last month.
