My husband and I are both late diagnosed Autistics. Much later than you!
We had 2 children already, he was diagnosed when our youngest was less than a year old, I was a couple years later (delayed by Covid).
Both our children are delightful. One won Student of the Year award out of 100 others in her year, their teachers all love the way (I believe) our Autistic natures have raised them... with manners, curiosity, with a respect for rules but to question unfair ones, with dedication to detail, organisation, artistic, observation and empathy for others, passion for reading and learning new things. They both are excelling at martial arts, combining focus, rules and art with fitness.
I don't know if they are autistic, they both show signs, but it's hard to tell with the fact children mirror parents. We are monitoring it, school are aware we are both autistic and to watch our children. One is having issues with selective mutism, but it's not impacting her that often.
We are unsure how to move forward with assessment, as assessments only asses you when you are already broken, it has no way to identify happy and thriving autistic children.
Which makes me angry on a level I never knew I could when I realised this point talking to my husband about it.
It's not all sunshine and rainbows, but neither is it a given you have to let go of the dreams you have of having children.
I struggle hugely with the playground politic bullshit, I don't like most parents, I hate with a passion the parties, especially softplay ones.
