I've just heard them, I think!
I've been round my mum's just to get away and to give her total peace and I've just got back, she's back in the nest, which is now slightly less high and more spread out than it was.
I think she might have "lost" them for a few minutes and that's why she was going nuts chucking bedding round.
Thanks for the support, this is a seriously stressful business. I'm at work tomorrow, I'll probably worry all day but at least I won't be wtching what's going all all day. I think I need to get out
