My DC all have additional needs and/or disabilities in some form, although one DC's needs are such that they don't affect his independence significantly and he is fairly low support needs (he only needs help with very specific things.....sorry to be vague, just trying to explain without being outing as his condition is more unusual!). The other two DC have higher support needs, while still being in mainstream school.
I haven't read the whole thread yet because I wanted to give my own thoughts without being too influenced by what others have said.
Mornings are hard and take ages. Getting more than one child with additional needs up and ready and to school takes a long time! I'm very lucky that my job is not 9-5 and involves home working, althoughis not 100% home based (don't want to give more specific details) but I would have been sacked by now if I had to start at 9am!
All of my DC have a lot of medical appointments and school/other professional support meetings, which means time off.
I often have to go and collect my children from school if they are unwell, and they have many more days off than average.
Two of my DC would not cope with holiday / after school childcare. My husband and I have had to arrange our work hours so that someone is always at home and not working when the DC are home. We have been very lucky to manage to do this, but it greatly limits our work options.
I need to use most of my annual leave to cover school holidays. I have a very flexible workplace and thankfully this is not a problem, but it could be a problem in many jobs.
I'm exhausted! Two DC don't sleep well, and I have my own physical disabilities and neurodivergence to cope with as well, which means I am more tired than normal even to begin with.
Colleagues don't understand (how could they? I don't blame them) and I try to put on a cheery, wide awake mask at work in an attempt not.to draw judgement for being shattered and emotional. This is very tiring in itself!
I can only work, even in the flexible job I do, because I have my husband. We have no other family nearby and if anything happened to my husband I would almost certainly have to give up work due to the DCs' needs.
I will have a read of the rest of the thread later as I'm sure I have missed things, but these are my initial thoughts.
