We crated Maisy at night for the first couple of weeks and we didnt get up to her at night either, however, every morning she had poo'd in there and the whole bedding, and her was covered, sometimes she had poo'd twice. She never cried in the night (that we heard). As she hadnt had her jabs when I nipped out somewhere she couldnt come I would crate her then and come back and she had poo'd again, so sometimes her bedding was being washed 3 times a day and when there are 3 children here my washing machines non stop anyway - dont mind so much if I can get it dry in the sunshine, but hey you know how the weathers been too.
Badger has access to the whole of the downstairs but sleeps on the sofa every day mainly, so Maisy would have been able to see him from her crate. Anyway, this pooing was beginning to get me down so we stopped using the crate and started using the kitchen at night. We still have the odd accident but it doesnt matter because she hasnt walked in it and although she didnt appear to be stressed by it I wasnt sure if she was or not.
Badger does get a bit miffed with her sometimes and does growl at her, although it doesnt put her off, he is deaf and has cataracts so cannot see (I remember posting in a thread of yours before). I think she would get the message if he could "put her in her place" but he is unable to. He enjoys being on the settee and at the moment she cant get up there and if we put her up there with us she jumps down and would rather be on the floor.
Anyway, when she is annoying Badger too much he starts barking, so I then "rescue" him by distracting her away and outside to play. I do in fact feel sorry for her because she just wants to play and doesnt understand why he wont play with her. At times when she is like this I will take her in the garden and play, take her for a walk, or take her up to my mum and dads to play with their Westie for 1/2 hour. Although it is HIM she wants to play with!
If I have to go out now and she cant come with me (which isnt very often) but like tonight my son has athletics after school and I want to go into school, I will shut her in the kitchen and badger is left with the living room and hall, I will not leave them unsupervised as I want to know they are safe and she may get too OTT with him as she is very excitable.
I dont know if its right or wrong doing what I do when I intervene but when I distract her I always say "Badgers had enough now, he's more of a great grandad to you than a big brother". I wouldnt feel responsible leaving them when she is at him in her playful mood and this has worked for us from day 1.
Good luck
