Real-life Application - research by Bowlby and Robertson changed way that children were looked after in hospitals, specifically to early adoption, mothers who were going to give the baby up for adoption were encouraged to nurse the baby for a significant period of time, by the time baby was adopted the sensitive period for attachment may have passed, making it difficult to secure attachments with a new mother, most babies are now adopted during the first week and research shows that mothers and children are just as securely attached as non-adoptive families ( Singer et al, 1985 ).
