Does anyone else's toddler eat with them at around 6.30ish?

[Gateau]

My DH doesn't get in until this time, so it has just evolved that this is the time we all eat tea. (my DS is 20 months).
And I must admit, we like it like this, although it does mean DS doesn't go to bed until 8-8.30 or even later.
But we seem to be the only ones who do this. Most people I know feed their kids at 5-5.30pm and then eat their meal afterwards when they are in bed. But this just doesn't seem to work for us. That said, I am thinking of changing the routine as lately DS is just not going to bed until about 10.30! I am worried he is not getting a proper wind-down before bed-time.
Does anyone do similiar to me?

We eat at around 6/6.30pm as a family and then the boys have a bath at around 7pm and have a story and are in bed by 7.30pm (on a good night)

Thanks luvaduck; it's kind of you to help out.
We'll try it all out, bar the bath bit. We don't bath Ds every day and when we do it's usually in the morning. Plus I find it hard to fit in.
