Thank you all for your comments so far... there were a few questions of clarification that maybe will help explain...
Nanny maybe I don't trust her yet... I guess that just takes time, maybe that's why I want her to do things more my way in the beginning til I can be sure that I trust her and that she can work with our family well?! I used a nursery for my older child before this and its such a difference. (In some ways easier, I could just drop her off and didn't have any idea of what she was doing until I got a report and random paintings at the end of the day!)
Erm, probably by most people's standards, small house... (3 bedrooms but they're not big, ex-council, I work at a desk in my bedroom, the baby and toddler each have a room cause cot wouldn't fit in my room) There is some space locally I could use for work but I am still bf once or twice a day (11am and or 2:30/3pm) so I thought it would be easier if I was at home but I beginning to think that I wasn't at home then she wouldn't feel like she had to get out the house all the time!
No tracking at the moment as I've mostly been around for her to tell me what she's going to do. She doesn't drive mostly walks to local things.
I really want it to work because actually we seem to get on really well (she is roughly the same age as me) and she clearly loves the kids and they her. There are just a couple of things that need ironed out but I don't know if I'm being controlling/ micro-managing!
fraktious I agree... a sleeping bag is a sleep cue... which is why I want that to be consistent. Is it unreasonable to ask her to put the baby in lighter clothes or sleeping clothes so that he is OK to have a sleeping bag also? It is cooler now anyway, so he might not even need a change of clothes as well as a sleeping bag? Also, I agree, I don't want her to be doing arty-farty stuff if she doesn't want to, it is more a desire that she stay closer to home in the couple of hours following nap time. (So playing at home, games, baking, being a fairy :), going to the local park... not taking them on an hour-long round trip on the bus for an hour of playing wherever they actually went... I still don't actually know because I'm trying to figure out how to address the issue...)
Onehang I think that I might do this, which was why I was annoyed that she rushed in, dropped the kids and ran off on Friday (although I suspect actually its because she didn't want to tell me where she'd gone; my daughter had a little bag of sweets in her pocket and a dummy in her mouth which I've made clear is for naps only...and a dummy in the baby's mouth too which we discussed would be use for naps time only in situations that he really really really wouldn't settle) :(
(Also, I thought that they were at the outside at park for 2 hours... in the cold, and dusk, which did feel like quite a long time!! OK for a toddler running around but not a baby in a pram.)
In the first week I printed out the kids routine (which I don't believe have to be rigidly stuck to, but just followed more or less) and she has not consulted it once. (I know this cause I found it down the back of the sofa at the end of the first day and she's not asked for it.) It is only a part-time job and her hours are 8am - 4pm, so really not a long day with no cooking really involved (only lunch which is usually sandwiches or leftovers of whatever, baby's food already prepared). So I guess maybe that's why I want her to follow what I would like for the kids. I really don't want her to feel like she can't do things, or has to get out the house all the time but the younger one is only 6 months old and I don't really want him dragged off all over the place. :( He's only small. (I feel she used the contraband dummy with him on Friday because he hates spending long times in the buggy and he would have been screaming the place down... to me that means don't take him out in the buggy for a long time, but I'm worried that for her it means 'give him the dummy'.)
TBH I probably mostly work from home so that I can see how she is with the kids, especially the baby. I know this is awful really.
I think ohnoshedittant might be right, I need to lighten up... (gulp) any tips for how I can let go but still feel that my kids are OK?!
