2 kids, 7 yr old DS with SEN (preverbal) and nearly 4 yr old DD. DH works away 2/3 nights a week. I pay for a couple of different people, let's call them Flo and Mo, to do a couple of hours mother's help at bedtime as I was really struggling with the two of them and exhausted.
Flo is about to stop for a while as she is finishing a course and it's crunch time. Mo is available easily and lives v nearby. She's not really qualified to do DS, but great with DD so I let her concentrate on DD and that frees me up to be 1:1 with DS who is pretty challenging. My plan was to up Mo's hours to cover for Flo. However, DD has been saying she doesn't like Mo any more. At first it seemed to be about wanting Daddy instead, but today she's been absolutely blunt she doesn't want Mo to come any more. I've tried to winkle out of her what in particular she doesn't like. She's been awful for Mo the last couple of weeks. I actually feel badly for Mo who is quite young and absolutely lovely. Mo is due to come tonight and I have no idea how to persuade DD to just tough it out for this time until I can find someone else. She loved her at first. Any advice appreciated.
