Hi Sandwiches,All of this is based on things I'vedone for my own DD, so if anything's not a good fit with your DD, please just ignore it. The questions are rhetorical, they are just things for you to ponder, not to reply with unless you'd like to discuss them further.Hopefully I'll have given you some ideas you can adapt specifically for your DD.
I can't help with the education 'how-to's' but Ellie56's advice is spot on.My DD had had enough after trying her GCSE English and Maths again during the first year of 6th form and just missing out again (C?) on the grade you need to continue A levels and she refused to do any FE. She has a load of co-morbids with her ASD and she also has severe fatigue. She'd never been able to do any physical stuff her peers did since being a small child, but it wasn't until she was at home 24/7 that I realised how bad her fatigue really is. 10 years on and we know it goes in phases, but even in good phases, bed, bath, chair days, we call them pyjama days, are commonplace. Depending how physically able and active your DD is will determine her lifepath from here.
Try and encourage a sport that's not based on teamwork, something individuals can do and succeed at theirown pace. Horseriding, archery, shooting, swimming some martial arts all have allowances for various disabilities, there will be loads more too.
Does she have a realistic career path in mind? If so, find out all the alternative ways she could approach getting the qualifications she will need for that, so if one pathway is too demanding, another may suit her better.
If not, and all she can see herself doing is nothing because she feels she's not good enough, why not teach her all the important lifeskills she'll need to function as an adult? In fact, do that anyway because they are too useful not to know.
Don't do this all at once, but gradually do it over time, while she's deciding her future. She'll be learning independence skills, but it won't feel as though she's learning.
she won't do anything for herself Are you sure? That could be an executive function issue, try thinking she can't, (not won't) because she doesn't know how to plan that particular task to get the correct solution. Then see if you can help with 'how to plan a task' YouTube is your friend, but plough through it yourself to find something she'll take on board, if you get her to look for it, she's likely to feel overwhelmed as there's too much info and she can't filter it easily to get the correct info.
This calculator is great for showing young ones how the household income is spent www.stoozing.com/soa.php and provides insight into the things she'll need to know to live independently.
Does she help with shopping, does she inventory the cupboards, fridge and freezer before you go so she knows what's needed and has a list ready?
Could she meal-plan and list the ingredients you'd need for a week?
Is she interested in food, could you both make a special meal every so often to share?
Social communication.
DD watched soaps from primary school age. Corrie and Emmerdale's plotlines were brilliant for teaching about the NT 'unseen but inferred' world which can be invisible to people with autism. A sarcastic comment with tone of voice that didn't mean what the actual words meant. Body language, facial expressions, pitch of voices, someone pretending to be a friend but plotting behind that person's back. Soaps illustrate so much that NT people understand but autistic people don't always pick up on. Watching them together and talking about them afterwards really helped DD to see a lot of the inferred things in the soaps and in reality that previously would have gone right over her head.
Does your DD have a favourite era? Can you get her to do some online research into it, watch videos etc. about it and discuss how different social norms were at that time and compare them to modern-day social behaviour.
How is your DD with phone communication with other people?Can she use the phone with confidence? Is she okay chatting to friends and relatives, can she make an appointment and make a note of date, time, location etc? Can she order goods, request help and explain the situation properly?If not, a few crib-sheets can help if she's flung into the situation, but a bit of pretend practise can teach and also be fun for you both.
How is your DD with face to face communication, conversation etc. Iappreciate now isn't a great time to try any of this, but keep it in mind for when things get more normalised. Can she answer the door if someone knocks/rings the doorbell unexpectedly, can she deal with an unknown caller competently? Can she ask for something in a shop? Can you role-play with her, firstly with you as the other person doingthe correct responses, then you as the other person doing indifferent or contrary or curt or plain daft responses so she's prepared for times when her expectations are not met but she has a plan to fall back on.
Plan B, or more realistically Plans B,C,D,E,F and G is what we worked on loads, a lot of the anxiety that drives autistic behaviour comes from unmet expectations. Life is so much easier if expectations can be more flexible or there are several alternative expectations instead of a single one.
Can you explain how watching the news and a few current affairs programmes can be useful for chit-chat in casual social occasions - again when that re-becomes a part of our life.
Does she have any sensory issues, if so, find out what she feels most comfortable with and what things you can do to make life easier for her. Loads of info herewww.falkirk.gov.uk/services/social-care/disabilities/docs/young-people/Making%20Sense%20of%20Sensory%20Behaviour.pdf?
Don't forget that she may be 18 physically, but emotionally she could be around two thirds of that, so make allowances for that when your automatic response to something she's done is to be exasperated and think she should be able to do that at her age
Ask her if she feels she'd be happier with a structured day and if so what would she like that to be, then both of you work towards implementing it.
