If you had a child with severe mental (and/or physical) disabilities with little to no chance for improvement over time, would you raise them or give them up?

1) give up to a licensed organization for kids with special needs, such as a single carer, group home, etc.
2) give up to a foster family who specifically adopts kids with special needs and have visitation rights
3) leaving your baby at the hospital/another safe haven/agency for adoption and letting them sort it out.

Would you judge someone for taking this route with their severely disabled child? If so, why?

What would you do if your partner took the opposite stance from you on this issue (ie. you wanted to keep your kid and they wanted to put them into care)?
