Friend and I have DC at the same school. Her DC has been hitting my DC during playtimes. School are aware and are dealing with it.
I feel disloyal keeping a secret from my friend, as am sure she'd want to know (I would, in her shoes) - but I think its best left to school to deal with as (a) they seem very on the ball with it and (b) its not happening out of school - DC's play together regularly quite happily.
I don't want to make it into a bigger deal than it is, and friend has enough on her plate with other stuff. Do you think IABU not to mention it? What would you do?
