I'm having a problem with Mason ATM where he doesn't want to leave.
If I take them to the park it's a major tanty when it's time to go home or if we go visiting, which is 10x more embarrasing.

I've tried leaving giving him plenty of warning eg 10 mins till we have to go. Then again at 5 mins.
What other tactics can I try as I've also tried saying goodbye and leaving him but he doesn't care and will run back to the park.
