So I chatted with my sister (a different one, we'll call her Tr - and she is on board totally with what I am trying to do).
Tr thinks that I should tell H that I am open to thinking about options and compromise, but that we just started this schedule and I think that we should ride it out for a month to see how it works. She thinks that letting him push me for change this early sets a precedent and that I should be open to discussing it, but recognize that I have been accomodating and fair.
I could also point out that regardless of the arrangement we have in place, there is always the chance that whatever activity comes up might be in conflict with the schedule and either babysitters would have to be hired or a compromise with the other spouse would be necessary ... having a completely free weekend doesn't mean that it's that weekend your friends are going to be arranging a party ...
