Ryan has complained for YEARS that she puts his family second to Bentley's activities. I know it is Ryan and all but I think, in general, that argument has some validity. Co-parents can be hard on kids. My kids have played sports with kids and mom signs kid up for baseball and then dad resents that mom has effectively scheduled the kid's time during HIS weekends because of games. I don't think the kid should suffer by not being able to do things because his parents are divorced but I also think that if your activities are getting in the way of having a relationship with your PARENT, that's a major issue. (I have also known custodial parents who would make it very difficult for kids to visit out of town parents during the summer because they were scheduled up with sports. "Oh, he can't come that week because he's got All-Stars." And now suddenly that month visitation is down to 2 weeks.)
I don't know what the answer to the problem is. I just think Maci doesn't care because it doesn't affect her. I'm sure Bentley feels pressure from everyone - Ryan and Jen and Larry to spend time with them. He likely feels pressured by Maci to put them off for sports.
