Thank you for bringing this up.
I met recently with an organization representing adoptive parents across the country, who are indeed eager to see this as part of a modernized EI program. I committed to them, and can commit to you, that indeed it will be part of the way forward, as we said it would be and, quite frankly, as it might already have been had we not been mired in a pandemic over the past year.
I don't know enough about the relationships of the particular family types you're talking about, but the idea, to my mind, is that it would be as inclusive as possible and reflect the way families are.
