OK, I fear I really AM BU.
I agreed on a nanny share with another mum at my DD's school (nursery).
I don't really NEED the nanny share, but it's helpful, good for DD and good for me to have some childcare (I have no family locally)
She is a lovely nanny, my DD gets on with both her and her other charge very well.
But, I hate not picking my DD up from school (she finishes at 11:30). I'm pacing up and down until I hear everything is OK.
I want to pick her up myself.
But, it's all arranged and I will have messed everyone about.
