Small baby's bed alight in the country (8)
I believe the answer is:
scotland
'country' is the definition.
(Scotland is a country of the UK)
'small baby's bed alight' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'baby's bed' becomes 'cot' (cot is a kind of baby's bed).
'alight' becomes 'land' (I've seen this in another clue).
's'+'cot'+'land'='SCOTLAND'
'in the' is the link.
(Other definitions for scotland that I've seen before include "North of the border" , "Clans dot the country, oddly" , "Country of Jock and Angus" , "Alban" , "Land of clans and kilts" .)
