Bit of a tricky one here.
My partner's 8 year old daughter is a lovely, affectionate and at times emotional soul. In what is a recent trend she's been calling him from mum's phone quite late at night for an 8 y/o (9pm, 930pm) in tears about something or other -examples are a dog that died three years ago and the fact my DP, who works full time with a long commute, didn't go to a mid morning event at the primary school.
During these calls, the ex wife is by the kid's side talking as well. The usual pattern is that I will hear the start of the call and what its apparently about, and then leave the room. I try not to mention it when its over as that means using up our scarce time together discussing the ex wife (I'm not having that, she's his ex wife, not mine).
Now for the last few weeks these calls are coming whenever DP and i are spending an evening together. We don't live together and both do 50-50 with our kids. We usually spend time alone once a week on Thursdays and every other Friday.
What should my position be here I don't want to deny a child access to their parent. Equally I'm not sure what is motivating exw and daughter to keep calling.
I personally would not allow my child (9) to call his dad after dinner time, not he's ever really asked. My ex and I have a good working relationship, respect each other's kid free evenings and trust each other to get on with it. If my ex couldn't put our kid to bed without calling me, I would have words.
