My kids Dad always picked them up at our house. Yes, my step kids are my kids. Their Dad and I always got along great until my wife took him back to court for child support. He got pissed and started talking bad about my wife in front of the kids and now they never see him. I would still let him pick them up at our house if he still saw them. I have a daughter from a previous mariage and had custody of her since she was 2. Now, if her crazy Mom ever wanted to see her, it would have been at a designated area. It all depends on your relationship and how much you trust the other person.
