Yes, Autistic people can 'make' a child just like anyone else.
Autism is a neurological variation, it doesn't prevent someone from reproducing just like a person of any other neurology. Autistic people are more likely to have Autistic offspring, especially if both mother and father are Autistic, but can also have children of different neurologies.
A person doesn't become autistic and being quiet doesn't make someone autistic - a person is born autistic.
Firstly, it's offensive for you to imply that autistic people are abnormal - autistic people are different to neurotypical people, not less than. A person is born autistic, it is not something that happens to 'normal' people or something that you turn into, you are always autistic.
It depends on the use.Autism as an identity is capitalized - for example Autistic person, Autistic child, Autistic community.Autism as a diagnosis or things for autism are not - for example autism diagnosis, autism classroom.
Genetic influences on autism are estimated to be around 74%-98%, so chances of an Autistic person having Autistic offspring is highly likely and a person of any neurology with one Autistic child may be more likely to have another Autistic child. There is no way of knowing for sure, we're not at a point where we can identify specific causes let alone how likely Autistic offspring are.
You can't - autism is an absolute, you are either autistic or you are not and there is no way that a person can become 'less autistic'. A person with autism can improve in areas such as commnuication, social skills, and functioning, this tends to happen naturally as autistic people get older and learn new skills, but it is helped by supporting and understanding the autistic person.
No one 'ends up' with autism - a person is born autistic.
Your autistic child may not recognise their name as their name. Many autistic people are disconnected from how they are percieved by others, not all Autistic people accept the name given to them as representitive of them.
The following numbers are approximations since different studies have found slightly different results. The chance of having one child with autism might be as high as 1 in 100. After having one child with autism, the chance of having a second child with autism is 1 in 20. After having two children with autism, the chance of having a third child with autism is 1 in 3.
Autistic people are normal - so yes, if both parents are autistic they may have an autistic child or a neurotypical child, either way that child is normal.
An Autistic is a person with Autism.
A person is born autistic - they do not become autistic.
This needs to be determined by you and your husband. Are you willing to have another child with the possibly of autism again? Can you treat both children fairly, even if one was autistic and the other wasn't? Do you have the time and energy to devote to two children, one being autistic? If you want to two children, then you should have two. But you just need to make sure that you ask yourself these questions and make sure that you and your husband can agree with each others answers. Your childrens lives are more important and it is also extremely important that you can equally provide for all your children and that all your children are treated fairly. You also need to make sure that even though your first child may be autistic, that your second child is not neglected because of the extra attention needed to provide for your first-born.
