First of all it depends how the two exes relate and communicate to and with each other. When they’re still friends and are able to show total respect and deliberate with each other how to respond when problems with the kids occur, then yes 50/50 may be good.
But continuity at school and friends is also very important to kids, so 50/50 under the condition they live close to each other is rather essential as well.

Best to put a Parenting Plan in place. If it gets to the courts, Orders will be put in place.

I came from a divorced family. We saw my Dad every 2nd weekend…to me that was nit enough. It depends on age of the kids and who they want to be with. I think week on week off can be too upheavaling.

It depends on the children and what they can cope with, which parent they want to live with etc.

if the parents live close to each other then a 50/50 split is preferred with alternating weekends so one parent isn’t always with the kids on the weekend.

Depends on the kids. Depends on the parents. Depends on their situation. Depends how everyone gets along. Depends how far apart they live. Everyone finds something different that works for them.

I have friends who do the week with mum, week with dad thing. They live 10 minutes from each other which makes things easier. I think kids need equal time with both parents, as long as both parents are both mentally, emotionally and financially capable if providing a safe place for their kids. It also depends on how the kids feel and what they want

So individual and depends on the location, how the kids feel about it and how well the parents get along. If you believe your kids are safe and happy with either parent then this could work out best for everyone.

I would like to know as well. I think it all depends on the kids and the family dynamic
