 This reluctance may also rest to a great extent on the overwhelming salience of the impairment in a setting where little else can be known about the future child. That salience reinforces the already-powerful tendency to see only the stigmatized trait. Botkin may express the dominant view among prospective parents in arguing that the burden of raising a child with a disability should be treated as equivalent to the burden of raising an unwanted child (Botkin 1995: 32–39).  Ferguson argues that the findings from research and from parent narratives in the past thirty years contradict such assertions and demonstrate that families with a child who has a disability look much like other families in terms of satisfaction, stress, and system functioning (Ferguson 2001: 373–95). Other research suggests that raising children with severe cognitive and other disabilities has greater stresses but similar rewards (Aschbrenner, et al. 2010; Blacher and Baker 2007; Gerstein et al. 2009).
