Here little ones develop in computerisation (5)
I believe the answer is:
uteri
'here little ones develop' is the definition.
(plural of uterus - where babies develop)
'in computerisation' is the wordplay.
'in' indicates a hidden word.
'UTERI' is hidden in the letters of 'computerisation'.
(Other definitions for uteri that I've seen before include "organs, in hospital patients" , "Places seeing early growth" , "Developing places" , "Organs for girls" , "Organs reproducing" .)
