Throughout the past decade, calls for experimentation and innovation in chi
ldren's services have proliferated in the US. The current tide of reform in
children's services is linked not only to shifting social welfare structur
es but also to transformations in conceptions of the nature of childhood an
d children's needs. Using illustrations from one demonstration project of '
wraparound' services, I suggest that these emerging programs may embed noti
ons of children as 'complex systems' - ideas that differ significantly from
accounts of child development as a linear, staged and goal-oriented progre
ssion.
