The board of county commissioners may in its discretion allow and pay to poor persons who may become county charges and who are of mature years and sound mind, and who from their general character will probably be benefited thereby, and also to the parents of children with intellectual disabilities and children otherwise helpless and requiring the attention of their parents, and who are unable to provide for such children themselves, such annual allowance as will not exceed the charge of their maintenance in the ordinary mode, such board taking the usual amount of charges in like cases as the rule for making such allowance.
