This arrangement was only more recent to enable me to work as I'm limited during the day but I'm no longer working and weekends will be every second weekend starting the coming weekend.
Not ignoring anything else you have said...just curious if the soon to change care arrangements for the kids i.e. from dad having the kids each week from Thur to Sun (all weekends-6 nights a fortnight) to EOW, means dads weekday time is increasing so he will still see the kids for 6 nights per fortnight?...as he does now? Can I assume that in spite of some communication difficulties...on some level...you and dad are able to reach agreements on your own for the most part?
