Hi, I don't know if this is the appropriate forum to ask this question but I'm in dire need of some advice.
My 4-year-old niece and 8-year-old nephew (not siblings) are inseparable, love playing together and get on well. They often get a chance to play together 4 maybe 5 times a week as their gran often babysits them and their siblings.
I have good reason to be concerned about their friendship (I won't state the reason on here). Therefore, I need to think of ways to break down this friendship. I'm not a cruel or controlling Aunt I'm just concerned about my niece's safety and well-being so I want to intervene before anything happens.
Can anyone recommend how I can perhaps get the two to play with one another less?
