I am starting to think ahead to school, which is a long way off as my boys are 15 months.
It dawned on me yesterday that it is very likely my boys will be the only children in their grade. We live rurally and the local public school has only 30 students at present. There are no other children born around the same time as them.
Issue or non-issue?

Non issue because they will be in a multi-age classroom so chances are the teacher will have them integrating with other kids and they will work in groups based on their abilities.

I went to a similar primary school as a kid and loved it!

Thanks Kaishi. I, too, went to a really small school (25-30 kids) and it probably didn't equip me very well for the real world. I struggled in high school to find my clique, and I wasn't pushed anywhere near as far as I could go. That was a lazy teacher though.
I guess my worry is not having my twins too dependant on each other, they are identical twins and I am starting to worry about them getting to High School and having no other friends beside each other.

It doesn't matter because you can't really change it!

I could change it - if I was willing to drive them 1/2 an hour each way to the nearest big town. But then that gets messy because they have 2 older sisters.

If the school is that small, are all the years merged with just one or two teachers? I assume they are so I do not see that it would be a problem.

2 classes, K-2, 3-7.
I suppose, like Crankybee said, there's no point worrying if I can't do/won't do anything about it.
Someone else started a thread about separating her id twins when they started school, and I am just getting jealous that she has that choice.
My dd2 is shaping up to be the only one in her grade, so I should be pleased the boys will at least have each other.
