Oh dear...10 is such a big number, isn't it? I can even remember high expectations about 10. And I can understand you wanting to get it right for her. Can the other kids take some of the load of planning and effort - I can't remember how old you said they all are?
I get the crying - done a bit of it myself, lately. I look back on the end of last year and how I felt completely fine and was running around organising everything and everybody - now some days I barely function. I want my life back! and I guess that's why we're doing this.
