Multiple birth, which is more common after ART than SC, has a
well-documented negative impact on post-natal maternal emotional
well-being (Fisher and Stocky, 2003). Baor et al. (2004) found
that mothers of ART and SC twins had similar psychological
well-being, suggesting that the psychological impact of mothering
multiples is unaffected by mode of conception. Mood disturbance
is more common in primiparous than multiparous ART mothers of
twins (Colpin et al., 1999; Baor et al., 2004; Sheard et al., 2007)
and almost universal in mothers of triplets (Garel and Blondel,
1992).
