DD won't go to school - anxiety

[PickledLily]

Every Monday it's the same, especially when DH is away. Her school have put strategies in place during the day for when she is in the classroom for when she gets overwhelmed (she's year 5), and this has been working well. I'm 3 weeks into a new (mostly home based) and demanding job and can't just take the time off, so she is spending the day moping around, asking what she should do but refusing any suggestions.
I'm at my wits end. Any suggestions to help get her into school?

10 mins either end of the day as a reasonable adjustment is vastly different to a part time timetable of e.g. half days which many schools have DC on long term without building up, some indefinitely. The latter should not be happening, is not in the pupil’s best interest, the LA should be providing alternative education as well if the pupil cannot manage full time school and an EHCNA should be requested.

Even if DD cannot attend don’t deregister. Parents often find it is easier (although not easy) to get support whilst on a school roll, crudely you are someone’s ‘problem’. Whereas, sometimes, it is all too easy for DC’s needs to be swept under the carpet if you EHE.

Another morning in school and she had a great time. Again she woke up saying she couldn't go in, and refused to get dressed until I said I'd race her to get dressed first. I had to keep her distracted to stop her reverting to worrying about school but we got there.
Someone asked if DH was hard on her and me too soft - DD says she doesn't like it when DH is around because he makes her go to school when she doesn't feel well enough. So I suppose I might be seen as the soft touch but then me saying no doesn't have the same impact as a 6' man with in a deep voice. If DH isn't around she will spend the whole morning saying she won't go to school and refuse to get dressed/ready.
What was noticeable was that DD was very calm after school. Normally she will have a tantrum about something and has always been more tired than her friends after school, although I've always assumed it to be hunger as she rarely eats much of her lunch (not enough time apparently though I think it's because she is talking too much).

Have a look at the Facebook page "not fine in school". Loads of information, support and advise xx

Half days still going well so far, thanks to the special task DD has been given, but it makes me wonder what happens when it ends as there will be no incentive for her to go in (unless I can get them to continue the task).
I'm hoping we can extend the school day rather than go straight to full time but DH thinks it's just DD being a master negotiator wanting to avoid a full day, and that the anxiety about school is just a phase (I hope so too) and she will get into the swing of it again once she's back full time. That we just need to be firm with her.
Any tips or success stories of children going back after part time schedules?
