My youngest DS has just turned 10. The majority of his friends are female, and every so often, he's asks for sleepovers with them - either at their house or ours. So far it's been one on one, rather than a group.
We had one at the weekend, and it was the first time I thought that we may need to think about stopping them in the near future.
He's a very young 10 - his current favourite thing in the world is squishmallows - and he is still very much pre-puberty. But it's only a matter of time.
When is it time to draw the line with sleepovers? And does it make a difference if it is one on one, or a group?
