For most parents, their child's move to secondary school is a big moment which requires planning, even more so for those with transgender children. The Victoria Derbyshire programme has been following two of the UK's youngest trans children for the last two-and-a-half years.
"I won't mention it, but if it comes up I will be honest. I'm not going to say, 'Guess what, I'm trans', but if someone mentions it I will say I am, because I am," says Jessica.
The 10-year-old's friends do not really mention the fact she has transitioned from living as male to female, a fact she prefers. She just wants to be treated "like a normal girl".
We first met "Jessica" and "Lily", who is now nine, in January 2015. We are not using their real names.
Jessica's stepfather "Alex" - who transitioned from living as female to male - says he is "taken aback, but quite proud" that she plans to be open when she moves to her next school in just over a year's time.
While it is not without problems, he says that approach avoids having to worry about whether someone will find out, which can be stressful for both the child and siblings who could accidentally "out" them.
"It's a big secret to keep. It just puts so much pressure on them. And so if somebody does feel that they can sort of be open about it, I personally I think that's a better way," he says.
