A 2 / 2 / 3 was what was suggested from L—LMFT suggested that that might be too much change, that it’s too abrupt, and too much shuttling.
FWIW I am currently favoring a 3-4-4-3 schedule as I would have the kids the same days of the week every week, with only one day rotating. I feel like its good consistency and stability for them to know where they are on each particular day of the week. As part of this I want to split the weekends in half and get one day each. Weekends are the best quality time for me and I don't want to wait 2 weeks to get it, I want it every week. Can't say I will like not having the kids for 4 days straight every other week, but I think any sort of 2-2-3 sched might be too much back and forth for me and a 7-7 sched is way too long at my kids' ages (7 and 4) so the 3-4-4-3 is a decent in between.
