Yes, I have had that 'they're growing up/I'm running out of time' wobble now and then. I try to put that energy into planning things with them that I've been putting off. I'm terrible at making these big lists of things to do, and then just leaving it.
Also making photo books or doing those hand-print things or those 'interview your kids and see what they say' things that are all over the internet to just take some time to capture that for later enjoyment.
user9086336 Fully getting that. I do think there are things that drive siblings apart without parents realizing it and I used to think if I didn't do the ones my parents did, then my kids would be so close -- and, well, they're nicer to each other than my siblings and I were, but that personality clash (and sometimes it's being too similar, sometimes it's being chalk and cheese or just being in different moods it seems sometimes) can just rub each other the wrong way no matter what. Can't really make them friends anymore than two unrelated people, some are just lucky and their parents support that well that it lasts.
Space for everyone to spread out, for teenagers to cook and entertain friends without us all being on top of each other- a place for them to exercise and hang out. Has prevented a lot of stress and conflict in my view.
Very much - my new home's layout with more separate spaces has been so nice in getting all of us out of each other's way, even though the square meter space isn't really bigger.
Over the weekend, my kids were playing card games (somehow very loudly) and I just read in peace elsewhere. It's made it nicer when we choose to be together when we've space to choose not to be.
