For any person to file as head of household, that person must pay more than half the total financial costs of maintaining the household, and also claim a qualifying person as a dependent.
If would be very unusual for any child to qualify as head of household, because they would need substantial earnings or investments in their own name and pay more than half the costs of maintaining the home. If a family is receiving outside financial support and the adults do not work but the child works, the child may have to file a tax return, but they would file as single and not head of household.
