For the last few weeks ds (2.3) has had some nightsmares... he keeps saying there's a brolly in his room. He mentions it in day time too. He said it this evening when he was drifting off, there's a naughty brolly in my room mummy, going through the tunnel. I have no idea what he's on about, I just told him I'd chased all the naughty brollies away. What on earth is he going on about?
