I have an autistic child too, and the below are based on my game plan. Your situation is likely different from mine and hence you should adjust it accordingly. Also, my game plan is still only half baked, in that it is not yet reviewed with a professional.
Before Age 18:Research guardianship or conservatorship appropriate for your state. You are likely to require assistance from a lawyer.
Age 18:She would qualify for Medicaid and SSI.
Medicaid and SSI eligibility is *very* finicky. That is where the 100k limit for 529a and income tests etc come in.
You may still be able to keep your daughter on your employer plan - but that will be secondary. This is a good setup - since medicaid billing rates are usually very low.
When you, or your spouse become eligible for claiming early social security benefits:Whoever turns 62 first should claim Social Security immediately. This makes your daughter eligible to claim SSDI-DAC.
Your daughter *does not* qualify for medicare yet. She will qualify once she has received SSDI-DAC for 2 years.
Be careful with SSDI-DAC and medicaid eligibility. SSDI-DAC payments are typically over the SSI limit, and it makes you ineligible for the medicaid as it counts as income. Many states has specific provisions in medicaid eligibility to allow the the eligibility to continue for this specific situation (e.g. CT, where I live) and many states do not (e.g. OH). You should research your state laws in this regard.
SSDI-DAC and medicare are lifelong once they kick in, and are *not* income based. The benefits for SSDI-DAC start at 50% of the primary beneficiaries PIA, and goes to (I think) 75% after primary beneficiary's death.
529a (i.e. ABLE accounts)Despite the 100k limit, they have a massive advantage - they can pay for housing expenses without impacting medicaid eligibility.
If you are in a HCOLA area then this is a huge thing.
Perhaps you can have the ABLE Account funded yearly with SNT up to the 15k limit and use that for housing.
Special Needs TrustThey are indispensable. My plan is to pay off our house in another 10-11 years and transfer that to the SNT.
Further, I'll likely fund the SNT with sufficient money to fund the following:
1. A yearly $15k contribution to ABLE account. This can pay "housing expenses" like RE Taxes, utilities etc for the house held in the Special Needs Trust.
2. Other expenses as detailed here:

However, once your daughter qualifies for SSDI-DAC, and Medicare - then there are no more income eligibility rules. However, there may still be other state and local benefits that may be impacted. So, is the whole SNT/ABLE setup still necessary? I don't know yet, and is a future research topic for me.
I had opened a bogleheads thread on this:
https://www.bogleheads.org/forum/viewtopic.php?t=283668Your daughter is only 7 right now. I'd suggest that you spend some time researching estate planning topics - maybe a little bit every week for a few years. This will make sure that once you are ready to go to a lawyer to actually create the SNT etc - that you have a good idea of exactly what your goals are.
