5Nowadays, she watches tv permanently.
Don't worry...She used to watch tv permanently, when she was a child, too.
We normally capitalise 'TV'. She watched 'all the time' rather than 'permanently.
With these changes, your sentence is possible. With 'when she was a child' we have a cut-off period. Her watching of TV now is a different thing.
Nowadays, she watches TVShe would
permanentlyall the time.
permanentlywatch TV all the time, when she was a child, too.
Secondly, we know that we can't use 'would' with stative verbs, and I would like to ask how to use it.
Nowadays, she lives in a small house.She would live in a small house when she was a child, too. (I think it is wrong, is that right?)
(I think we must construct that sentence with 'simple past' because of the stative verbs.) You are right in assuming that your sentence is wrong.
Nowadays, she lives in a small house.She lived in a small house when she was a child, too.
