So what is your care % according to child support / family tax?
Look, if 5 a fortnight mid-week works for you, maybe you wanna count your blessings.
Sometimes, our own emotional scars stop us seeing things clearly... So I am reading between the lines - yup, you want more time... But the ex is accommodating you by not forcing you to take weekend time when clearly your work commitments don't allow it. That is a win...
Much better than her telling you that you have to do weekends because she knows you can't....
