So we're a pack of long time friends (15 years+) and we hang out with each other many times. The meeting place (if we don't go out to town) is one of our houses, and we rotate it (so no one is forced to clean after us 4 times a month :) ).
One of our friends has a kid (1,5 years old) and since it happened he became reluctant to go anywhere (either town or our houses). While we perfectly understand why (kid, especially small is a lot of work), we tried to explain to him that surely he can ask either grandparents (his or his wife) to take care of the baby for one night once in a while (or hire a nanny) and we can go have fun.
However, he insists we meet at his place and for a time we did (after the baby was a little grown). But we think a bunch of "alcoholized" guys and gals is not the perfect company for a kid; also, when we go there, he and his wife aren't even with us most of the time (you know, baby is crying, change diaper, feed), we can't do any loud things, the kid wakes up every 2 hours and they bring him to us to play "with uncles and aunts". The house also is, to lightly say it, a mess. If you can find a spot that the kid hasn't vomited on/smeared some chocolate or something it's a lucky day.
We're happy for them, but for us this is whatever limited time of week we have to relax and when we meet at his place it's anything but relaxing. Playing with a kid for 30 min can be fun, 6 hours is not. Constant interruptions as well.
However when we suggest that we meet at any other place they state they can't come, and then are annoyed that we don't want to hang out with them ("you can come to us").
What we're looking for is basically a way of saying "Look, we're friends with you, not your kid. We're happy for you, but you can't force those interactions on us, we want to have fun not play grandparents".
