It sounds like you are doing everything possible to make this arrangement work and you are clearly a loving father. I really hope you can make a 50/50 arrangement work as I really think they offer a lot to a child in the form of regular consistent contact with both parents.

The only thing that jumps out at me from what you have said is the days you have your daughter change from week to week. I wonder if this is affecting her in that she feels she never knows where she will be? Maybe a more structured arrangement (like you have her Wed, Thur, Fri one week, and Wed Thur Fri Sat the next week, then back to Wed Thur Fri the following week) would help her feel more settled. I have seen arrangements like this work really well in other 50/50 custody arrangements.

Good luck with it
