Can children with disabilities get social security disability SSD SSDI SSI benefits?

The following answer is from:

A child with a disability age 18 or older may get Social Security benefits when a parent gets retirement or disability benefits. The child also can get benefits if a parent dies. The child’s disability must have begun before age 22.

The following answer is Attorney Walter Hnot’s annotated response to the previous answer.

Also, children under the age of 18 utilize SSI as their main form of disability benefits.  Just remember one important thing.  Children seeking SSI go through a deeming process, where the parent’s assets are analyzed.  If the parents make too much, then the child cannot go onto SSI.  Remember, SSI is a poverty program, and since most children under 18 do not work, we need to assess the parent’s income, as the child is likely living with their parent’s financial support.
