Cr Butcher's grandson, Rafferty Jarman-Shirkey, spent time at the annual plan hearings on the first morning of the three-day exercise in public consultation.
Cr Butcher said she had not asked approval from Mayor Peter Chin, other than notifying him before the meeting.
"He said `Good'. He said he'd make more sense than anyone else," Cr Butcher said, hastily adding he meant councillors, not the public.
A "full-time caregiver at the moment" of her son's child, Cr Butcher said bringing a child to the meeting was somewhat stressful, particularly when Rafferty started talking while others were talking to their submissions.
Whether she would bring her grandson today "depends on what my husband's [architect Ian Butcher] diary says at 9am".
