One limitation of Bowbly's monotropic theory is that the term monotropy, lack validity. Schaffer and Emerson found that although most babies did attachment to one person first, a significant minroity formed multiple attachments at the same time. Also, although the first attachemtn does appear to have a particullay strong influence of later behaviour, this may simply mean it is stronger, not neccersirly different in quality from the other child's attachments. For example, all attachments to family member provide all the same qualities such as emotional support and a safe base. This means that Bowlby's theory may be incorrect but their is a unique quality and improtnatce in the child's primary attachment.
