Referencing a group run by a sculptor who isn't trans, doesn't have a trans kid, has no experience working with trans people, and has no qualifications in the care of trans people, and whose organisation thought it was a good idea for children to put transphobic stickers on their school books, does not further your case:
Transgender Trend is, "are an organisation of parents, professionals and academics based in the UK who are concerned about the current trend to diagnose children as transgender, including the unprecedented number of teenage girls suddenly self-identifying as ‘trans’ (Rapid Onset Gender Dysphoria or ROGD). We are also concerned about legislation which places transgender rights above the right to safety for girls and young women in public toilets and changing rooms along with fairness for girls in sport."

Transgender Trend's evidence was accepted as intervenor by the High Court Bell vs Tavistock Judicial Review.

In 2016, Transgender Trend asked how a child could give informed consent to a pathway that will shape their whole life:
To be in the position of having to make this decision is an unenviable one for parents but it’s especially worrying when the decision is handed over to the child. Of course, a child needs to be informed and their view ascertained before any treatment, but really how can a child begin to understand the complexity of this issue, the life-long effects of treatment which even the adults don’t know, and the reality of life as a transsexual adult?
In 2020 the High Court agreed. (Bell v.Tavistock, para 151,152.) Why did the GIDS not listen to the voices of caution over those four years?
