Based on in-depth interviews and fieldwork, this article examines mothers raising kids with invisible, social/emotional/behavioral disabilities to refine feminist theories of mother-blame. The mother-valor/mother-blame binary holds mothers responsible for families and future citizens, maintaining this “natural” care at the center of normative femininity. The author explores how mothers raising such burdensome children understand their experiences and makes three arguments: Fewer mothers are blamed for causing their child's troubles in an era of “brain-blame,” but more are blamed as proximate causes if (...) they do not make unrelenting efforts, paralleling “concerted cultivation,” to resolve them; such mothers often exceed concerted cultivation, as they seize authority, as vigilantes, within educational and medical systems in the midst of turf wars, cost containment, and a resulting proliferation of medication treatments; and this maternal speedup holds mothers accountable for feminizing ties to sons, for policing gender boundaries while policing their own feminine care. In sum, mothers raising invisibly disabled kids may represent the model of maternal valor for an era of public stinginess and extensive medicalization. (shrink)
