I have sent several like this since this in the 2 yrs since we split. He has moved on (mainly because he had the freedom to do so!!) and has new DP and new DCs. But actually he prob sees our DCs about the same as he did before he met her so that's not really the issue. (just has more excuses).
We made an agreement as part of our divorce and he has basically never stuck to it in the spirit it was intended. He always insisted that I work full time which imo meant sharing parenting duties when we were together (that didn't work). Now I am resident parent so the bulk falls to me but do expect him to have them more than 24 hours every other weekend and one early evening per week!

'xxxxxx October 2008
We are holding our 'event' that day. Are you available to pick up xxxx that day? I won't go to the dinner but I will go to the drinks after the event if possible.
days from October to November 2008
I am required to stay late on these evenings. Can you make that the day you pick up during that period?
General weeekend arrangements
I am assuming that you will be having boys of weekend of *th September. We need to define (again) what is meant by a weekend. I think it should include two nights ie Friday and Saturday. This gives DCs a longer period with you, which helps them in all ways and enables me to do something meaningful rather than just piecemeal stuff as I have done so far. Because your definition of a weekend appears to be 24 hours!
What is your intention regarding football on Sunday mornings on the weekends you have the boys?
(last season he took my DS twice and that was after nagging from me - so it meant on his weekends I still got up at the crack of dawn to drive my DS1 to play football for his team)
I really think you should consider what is fair to both them and me regarding these arrangements not just what suits you.'
