i guess i'm just surprised at the assumption that the women are in the wrong here, droves. they're all of them dense beyond belief for not having had a document covering this, but i guess it's like omitting a pre-nup because you believe all promises of undying love will be kept to.
in this case he's not kept to his promise (not too surprisingly, i might add) but they have accommodated that and he is welcome at family occasions/christmas etc... i just think that asking for more in a legal setting before the mothers are ready to make that adjustment will have turned a bad situation worse. i'm going by what their QC says about him being welcome etc, that's not supposition... so to me it does sound like a salvageable friendship that won't be salvaged now. regardless of whether the five hours is in their house or alone with the child, that's something that can be built on when the child starts to voice an opinion.
i can totally see why it seems unfair and imperfect to him but i'd say for the longer term relationships of all concerned (not least the child) that backing off would be the smart move, for a while, until the mothers have to refuse their child to see more of him. which they won't, imo, if the dad is their friend.
that's the advice i would give a pal of mine in this situation. no court, no guns blazing, do everything you can to retain proper friendship until such time as the kid gets a say. but then as i have said, our pals have had their ups and downs in their parenting of their children, but it all works swimmingly now thanks to lips having been buttoned and playing the longer game.
