I did it with dp.

Whilst time outs didn't suit ds, - the attitude to consistency and guidance of the children behaviour was very good and we apply alot of that to both kids.

We actually worked out that ds needed 25 mins of timeout to calm himself. Any shorter and it would interrupt his 'cooling down' process - but that's just ds.

Give it a go, I found being in a room full of other parents with issues was terrific - you don't feel so alone
