Help. Had horrible weekend with ds who scratched dd(2.5yrs) so badly on face during row that she now looks like has been mauled by cat, pinched and punched friends, and generally been a horribly behaved. Have responded by isolation - (room of doom), withdrawl of nice things, and long talks about behaviour. Historically was a biter, basher etcc.. I thought we had entered a new faze as all this behaviour seemed to be on the back burner but last few weeks it has returned. Should I just book his place at bostal now? Advice please - what am I doing wrong?
