Kids custody/one-on-one time

I'm asking here because I'm not sure where else to ask. I googled and did not find the information I had hoped. We currently have a 2-2-3 schedule with the kids. We have two. A daughter 2.5 years old. A son 9 months old. We would like to spend time once a week or ever other week one-on-one with one of our kids. We are not sure how to do this. If anyone has experience with this and could help I would appreciate it. If anyone knows of resources online that I could read through I would appreciate it. One idea we had was to pick one day a week and just take one for a couple hours and bring them back. Would overnight be better? Not having a set weekly schedule for one on one time and just do special events? Any and all suggestions are welcome! Thank you all for reading and any help you can provide. :)
