This study examined the association between perceptions of children's care needs and maternal sensitivity with 76 dyads in foster care. Foster mothers were more sensitive to typically developing children perceived as requiring easier care and were less sensitive to children with developmental delays. Adopting foster mothers were sensitive with children requiring complex care. Older children were perceived to need more care and to be delayed in development. Nearly half of the sample were perceived to be developmentally delayed. Foster mothers were less sensitive to children with multiple placements. Perceptions of caregiving needs can influence the quality of interactions. (Contains 1 table.)
