Aw thank you Mint. I think so, but I could be a touch biased. 
I have come on this morning to post a massively positive update. 
This morning I have been working upstairs in the house, as both boys now have the pox and are in bed. I have been up and down a few times, but more up than down over about an hour and a half, with the last stint being quite long, as I was trying to tune in a tv and dvd player for the poorly boys and .... not a peep out of Pip! 
When he was in his crate he used to whine and get louder and louder until he was really yelling, starting the minute he heard the living room door open, but this morning, having free range of the kitchen and a nice snug bed, he was absolutely fine.

I left the kitchen door open, but closed the dog-gate and he was completely quiet, except for the very last time I went up, when he did one little whine - I just said "Quiet, in your bed." from the stairs ... and he did! 
I left him with Mum this morning while I took dd to school and she said he was much quieter. He used to finish his breakfast and then start to whinge before starting his kong - basically as soon as he noticed I wasn't there, but this morning, he just ate his breakfast, then lay down in his bed with his kong and he was still happily stuffing his face when I got home.
Next week will be the big challenge, when all 3 dcs are finally back to school and I have to leave the dogs home alone for the school runs again after over a month of hardly being left at all. Am feeling much more postive about it now though.
