oh wow I am going to bookmark this- interested to hear what others say. My son is 6, with autism, and is non-verbal. He just sarted kindergarten/ life skills (I held him back a year). I left his father right before he turned 3. Our schedule was horrible for a long time- it set into a weird a/b week thing where the weekends were split in half, and basically did a flip-flopping 2 day on/ 2 day off thing. It was totally inconsistent and they outgrew it obviously by 4/5/6. It was- and is- "50/50", not that I feel that it is truly even nor a good idea. He works long hours- when he is working- and often it is actually his live-in girlfriend caring for my boys. I do the majority of the transportation (don't even what to get into that), and I handle ALL of his therapy/ school/ etc schedule/ meetings/ application/ etc. All the time. But ex has always insisted on having 50/50 so it is "fair" and because he doesn't want to pay more child support for them to be with me more- even though that goes to feeding and caring for them, not petty cash in my pocket! before i did anything drastic I finally got him to agree to a more consistent schedule- its a 5: 2: 2: 5 schedule, I have them every m-t, he has them every w-th, and we rotate weekends f-s-s so that we have them 5 on, 2 off, 2 on, 5 off, etc. I think it is more consistent and easier for the kids to understand that what he were doing before, however it is still not ideal, especially for my son with ASD.
If I were you I would consider attempting to get primary custody. The main reason I haven't gone there yet is because I witnessed my husband's ex drag him through a completely unnecessary and ugly custody battle (where she lied and it was obvious she was financially + power- motivated, and lied about most things and used my autistic son as cannon fodder), and i saw how devastating that was to my husband. His son is NT and was doing great in their 50/50 schedule. My story is completely different, but I saw the devastation in it and It worries me.
Some day i might go there, it's just hard to do. better to start off there then try to change it later!
