Just found out from ds6 that the nanny has been shutting the bedroom door on him and letting him cry at bedtime (he is scared of the dark). Dd shares room with hard to settle younger bro and nanny asked what she shd do to stop him bothering dd and i said stay in the room (i do gradual withdrawal). But it seems she is just shutting them in which upsets them both. And not telling me. Thoughts?
