a thing I love about the TransDanny headcanon: there’s a photo of Danny and Maddie when he was little, happily dressed and presenting as male, meaning that his parents either accepted him as trans from a young age, or allowed him to dress himself and have his hair done as short as he wanted and not forcing him to conform to gender roles, which allowed his coming out to be a lot easier
did he have a phase where everyone just called him a ‘tomboy’? or did he announce that he was a boy early on and that was that from then on? did he start school as Daniel or Danielle? like maybe it was one of those kids will be kids things where he wanted to be a boy for a day and his parents were like, 'aww that’s cute we’ll let her have her fun’ but a day became a week, a month, a year, he never grew out of it because he was never just playing pretend
personally I like to think that it started with Maddie and Jack just having super lax views on gender roles, unsurprising since Jack loves knitting which he might have been made fun of for because it’s 'feminine’ and Maddie is very strong and self sufficient and grew up with a big tough sister who wears her hair short and acts very 'masculine’, so they already have experience subverting traditional gender roles
so when they have a daughter who drags them to the boy aisle as soon as she’s old enough to choose her own clothes/toys and asks for a short haircut like that Chip Skylark guy who sings about his shiny teeth on tv, Maddie and Jack are just like, yeah sure why not? their kid can look however she wants
Danny was able to present as male from a very early age, his parents treated him and Jazz equally regardless of gender and I feel like maybe he didn’t even think to ask to be referred to by male pronouns until he got to school and the kids immediately assumed he was male and he realised ho dang, this feels RIGHT.
and then he’d have the teachers calling him Danielle and referring to him as female and another kid is like, umm Danny’s a boy tho?? and the teacher looks at this little boy with little boy hair and little boy clothes and is like, oh uh sorry kid there must have been a mistake in the paperwork, was it supposed to say Daniel?
and he’s just like yES YES DANIEL THAT’S RIGHT THAT IS MY NAME ALWAYS YEP
but then he feels bad because technically he 'lied’ to the teacher so he goes home and doesn’t say anything because he thinks his parents will be mad at him for lying on his first day at school
and then the parents get a call from some very confused school staff asking whether or not they’d enrolled a boy or a girl because they had a Danielle Fenton in the paperwork but a Daniel Fenton was dropped off to class this morning and that’s when Maddie and Jack were like… oooooh okay so this is how it is
they tell the school that he’s definitely a boy, always has been, they don’t say he’s trans because they probably don’t even know that word exists but they do know that their daughter seems far more comfortable as their son and they don’t see a problem with that and as far as they’re concerned it’s none of the school’s business
they’d probably sit Danny down for a talk after that in which he starts crying and apologising and they have to spend about ten minutes ensuring him that he isn’t in trouble for lying at school and if he wants to be a boy that’s okay they can call him a boy for as long as he wants, he just has to let them know if he changes his mind but if he doesn’t then that’s okay too, they just want him to be happy
and from that point on he was pretty much just the Fentons’ son, his parents would buy him binders and do research on trans kids to make sure they were doing the right thing and as soon as he was old enough for T they said they’d support him whether or not he wanted to take it and if there were any complications it was okay because he was still their boy no matter what his body looked like
I mean just, the Fentons have fucked up a lot of aspects of parenthood so I just really really REALLY want them to have done this one RIGHT or as right as they possibly can, they might be quite scatterbrained and neglectful at times but it’s clear that they really do love their kids, and were probably a lot closer with them when they were young, so it makes sense to me that they would be accepting of Danny’s identity even from such a young age
all they want is for their kids to feel happy and safe, which means when they find out he’s half ghost it still doesn’t MATTER, because they already promised they’d accept him no matter what
