Children's home bosses have been urged to use more "gender-inclusive language" to avoid offending transgender patients.
As a result, the chiefs were told not to call residents "boys" or "girls" at all.
The Care Inspectorate confirmed that those employed at children's homes across Scotland must always use such language.
In guidance supplied to the homes, the report has said that the phrase "come on, boys and girls" was not considered "good LGBT practice".

Instead, staff should say: "Come on, everybody."
The guidance reads: "Try to create an environment that feels safe to explore identity, and enables young people to change their mind in future if they wish to do so."
Additionally, it tells staff to set up scenarios to allow children to say their pronouns - by employees introducing themselves with their pronouns, for instance.
Slamming the guidance, founder of the Free Speech Union Toby Young accused the Care Inspectorate of "telling carers to affirm the delusions of children".

"If I was a gender-confused adolescent in care, I'd want to speak to someone who could give me some sensible, practical advice, the kind of advice a loving parent would give," he said.
Young explained: "Ie 'Don't embark on an irreversible medical pathway until you've really had a chance to think this through."
After the new guidance was issued, a spokesman for the Care Inspectorate said: "This guidance was developed following requests from services for children and young people for guidance to help them support transgender, including non-binary, young people in their services.
"Every day, the staff of these services must, and do, find ways of helping all young people to feel supported, loved, valued and respected."

He added that the organisations expects all services to develop and adhere to "inclusive culture and practice which creates a safe space and takes appropriate account of the wishes, rights and needs of all young people".
"We have a duty to support services to ensure high-quality care for all those experiencing care. We have based this document on a range of legislation and current good practice guidance, referred to throughout and detailed in the 'useful references' section at the end," he said.
The latest row on free speech has broken out after the Care Inspectorate came under fire when it said girls under their care should be allowed to share bedrooms with boys who identify as transgender.
Cathy Larkman - who is a former senior police officer as well as the national policing lead for the Women's Rights Network - said: "I don't normally call for anyone to lose their jobs, but everyone involved in this decision should be removed. They aren't fit for their role."
