How impt is it for dd to know other children before starting at primary?

[Travellerintime]

Hello,
dd (4.7) will start school in Aug. We moved house end last year, but kept her in her old nursery for continuity. As her old nursery is not that near where we live there is only one other girl from her nursery going to the school. This girl is a good friend of my dd, but it turns out that they're not going to be in the same primary class.

I thought I had accepted the fact that dd wouldn't know anyone at school and kept telling myself that she'll be fine. But now I know there IS someone there but they're in a different class, I keep worrying about it.

Here are my questions:
Should I phone school and ask them to consider putting dd in this girl's class? i don't want to seem a pushy parent - I've already been on the phone a few times because of late placing decisions - feel they'll start to sigh if they hear me on the phone again.

Or does it really matter? If dc DON'T know anyone, is it an issue? Is dd still likely to settle ok? She is quite quiet in large groups, but conversely has pretty sociable impulses.

Help! I feel I'm getting pretty wound up about it all.

Thank you all for your support. I am feeling much more positive about this.

Dadatlarge - suspect you are right; I am far more anxious about this than dd will be. Although quiet, she is quite resilient and I'm thinking now she'll be fine.

Cat64 at being thought a desperate loon! Although, I think I'd be happy if another parent went and did this - at least it'd help me!

Fwiw, we went to a parents evening earlier this week, and the school seems quite keen on facilitating parent friendships as well as children's - with a social planned early in the new term. So this is quite encouraging as this could help me get to know parents for kids' playdates.
