Hmmm... it is possible that the 'no shouting' thing was meant to reassure you ECATLM... as in, telling you that she tries to keep a nice peaceful environment for your baby, not older kids yelling at one another and your baby getting pushed around... Not sure, but trying to see how it could be more positive for you.
TBH, the lack of warmth and cuddling would put me off more. But maybe she's more cuddly when you're not there. Maybe she feels a bit inhibited being all lovey-dovey with your dd when you're watching. I know I was really unsure about using a cm (used a nursery till my dds were 3 and 18 months, when we moved houand couldn't find one to take them) because I didn't want my kids to have an 'alternative mother'. I preferred a more 'institutional' setting (and have to say that the old nursery was great, not at all 'institutionalised' actually) than a single 'other female' to whom my dds would become attached.
But now I can see that I was wrong to think that. They have bonded very deeply with their cm, they genuinely love her and are confident enough in her to turn to her without reservations if they are feeling unwell, hurt, frightened, or whatever. But they still know I'm their mum...
I have digressed wildly, sorry. But I was just thinking back to that first settling-in period and wondering if maybe what seems like 'stand-offish-ness' is really an attempt not to 'muscle in' on your dd in your presence.
Well... that's a more +ve way of looking at it. But obviously only you have seen what she's like, not only with your dd but with the other children she looks after. I still feel, though, that gut instinct tells you a lot. We interviewed about 4 cms when we moved house, and I just knew that one was the right one. Nothing specific, in fact she scored less than some others on certain grounds (e.g. she doesn't have a garden, that kind of thing), but she just 'felt right'... and I'm so glad I went with that.
Hope you get it sorted out and that your dd is happy.
