how can he justify telling a 5 near 6 year old to BUGGER OFF??
Are your children likely to have been impeccably behaved little angles?
As siblings, do they share well? Deal with conflict and disagreement with good grace and patience?
Are they able to notice subtle language and tone to know when they have out stayed their welcome?
Mine have never played on the street till now so I'm very new to this territory
Wait until the time comes that you have several extra children to parent in your house, including squabbling over excited siblings, day after day after day after day through the holidays.
The feeling that you are being used as free childcare can make parents bitter and resentful towards the other children's parents.
There are lots of social niceties to understand when your kids are playing out. And it's not just about the playing out and it's nit just managing the relationships of the children involved.
If you're new to this, you've just not got the subtleties yet.
