50/50 is perfectly good for the children, providing it doesn’t affect the child’s routine – i.e. going to school, seeing their friends, regular activities, etc. If it is unsettling the child too much (depending on their age) you might want to ask them what they would like. It may be best to say Fri nights/weekends, holidays, etc are spent with one rather than the other, providing that parent also gets a fair amount of social time, not just day to day school time, which isn’t fair. 50/50 is always a happy medium if the parents can be civil.
All the best, sounds like you’re having an “easier” separation than most who post around here, so keep going down that route – that is what is best for the child.
