We've found it effective, and it's good to have a chance to spend more time raising the kids. At this point, it's also because since things are being upset already, I hate to do more to unsettle their lives than we already are.
Consider that it also means you have to put in extra effort for them to socialize (play dates, group activities). This is something you get for free with regular school. It's nice you want to spend more time with your kids but it's also important that they have alone time in separate social circles to properly develop social skills. There's still plenty of time to spend after school and on weekends. :)
