I just wanted advice really as my ds 5, as he has started talking to and about his imaginery 'brother' he has given him a name and talks to him now and again, while I was in the bath this morning he bought his brother in as well and introduced us, I didn't know what to do, I dont know wether to ignore the friend, or talk to it, as I dont want to encourage it.
I know that its not uncommon for children to have them, just wanted some advice and insight as to why they have one.
TIA
