Deciding I really wanted this to get answered I started googling around.
"Federal child labor laws set a minimum work age of 16 for most occupations, but the laws exempt minors who work in the agriculture and entertainment industries. Unless states pass their own rules, children who are 12 can work seven days a week outside of school hours picking fruits and vegetables. Age, hour, overtime and minimum wage provisions of the federal Fair Labor Standards Act that protect young workers in other fields don't apply."
Child Work: Agriculture, Entertainment Fair Labor Standards Act Exemption - Stateline
Though mostly applied to farms, it's quite interesting how we allow our children to do work we condemn other, often developing nations, for having their own minors do. Especially given how when we ourselves were a devloping nation, we used child/slave labor too just as modern countries are doing.
More to my original question is this,
Trafficked for Forced Household Labor, Not Family Chores
"Upon arriving in the U.S., LV, a sixteen-year-old girl from Ecuador, expected to go to high school and be paid to provide childcare for the family with whom she was to live. Instead, the family that brought her to the U.S. did not permit her to enroll in high school and, for over two years, forced her to work as a domestic servant in their home, providing daily childcare and performing household tasks for no pay.
When LV brought claims of trafficking and forced labor against the family, a New York federal court found last year that the forced work was not work at all – in part because she had a “close familial relation” with her traffickers. To the court, LV’s domestic service was akin to chores because her employers were extended family members.
But, as detailed in an amicus brief filed by Columbia Law School’s Sexuality and Gender Law Clinic as LV appeals her case, this practice, which has young people working as barely paid servants for employers who are – or appear to be – family members, is not infrequent."
So it seems that yes indeed, you can force your own kids or relatives to do what amounts to slave labor. Would seem that once again, as in times past, where our own interests lie, standards we demand in other countries aren't demanded at home.
