'didn't forget' is the definition.
I know nothing about this answer so I can't judge whether this works.

'confined to the home to look after' is the wordplay.
'confined to' becomes 'kept' (I can't explain this - if you can you should believe this answer much more).
'the home' becomes 'in' ('he's home' can mean 'he's in').
'to look after' becomes 'mind' (I've seen this before).
'kept'+'in'+'mind'='KEPT IN MIND'
