Our son is 3 years old and my ex sees him every week. On my weekends he gets him for dinner on the Wednesday night preceding, and on his weekends he has him from Friday 2pm-Sunday 6pm. He also gets him for 2 two week increments in the summer and we alternate holidays/holiday breaks. My ex is trying to push the issue on FaceTiming nightly which I don't think is reasonable. Our son doesn't want to FaceTime him usually and will throw a fit about it or literally try to hide from me with the phone. The only time he's been okay about FaceTiming his dad is when I've caught him off guard while he's in the tub and has nowhere to go basically. But, that said, I've explained multiple times to my ex that our son has a routine here and is bed no later than 8pm, but my ex will force the FaceTimes to go on for 40 minutes or more after multiple attempts at goodbye on myself and my sons part.

Sorry this is lengthy lol. So basically my ex sees our son every week, and I don't blow his phone up when he has him. We have a high conflict relationship and interacting with him is always a hassle and anxiety producing due to a history of verbal/emotional abuse. How often would you all feel FaceTime is reasonable?
