DS was 4 in November and has just started going mornings only to the school in our village. It has a termly entry, and children can start going there the term after they are 4, doing mornings for two terms and then going full time the term they are 5.
There is a pre-school in the village, where children go from 2.5 until the term when they are 4 (I don't think anyone stays any longer, as they all tend to go to the school in the village).
The children in DS's class are a mixture of morning only children and full time (it must be more peaceful in the afternoon ).
So, what is the likelihood of it being a problem for us to go away in late June? If DS were at pre-school I would have no qualms about it. And if he were in school full time I wouldn't think of taking him out. Would he count as an unauthorised absence anyway - as he isn't in school full time?
We really like the school and don't want to be awkward parents (but would still like one more year of not having to go on holiday in school holiday time...)
