Can I really work from home with a nanny who brings her own daughter, or will the house be overrun with toddlers?

[oranges]

I'm interviewing for a part time nanny next week, and have never done it before. I work from home and go out for meetings and the idea is that I'd shut myself up in the study, while nanny takes care of ds1 and her own one year old daughter. Is that possible, in a two bed flat with no garden? Or will my one year old and her one year old ruin all possible concentration? And what should I pay her?

oh arse now I have LOST an apostrophe

fgs don't tell Greeny

this would-be nanny lives too far away really to drop in to her house in the middle of the day and I don't think I want ds shunted on and off buses all day by someone else.

just went to the park with ds and saw the nursery that I was considering bring all the children there for morning playtime, and they all looked really happy and confident, and the staff were all laughing and playing with the children (wwhhhr, sound of my mind being made up).
