P.K.
Oh man...that's hard. I feel for ya.
Society makes it so hard for families (especially with evening activities)to find the time to stay connected. I've heard of these things helping people.
Perhaps your entire family needs to slow down a bit. Stick to one activity per child. Maybe too late for the fall season of activities, but there is hope for getting a handle on your families future schedules.
Study's show that a a set time for supper everynight helps children feel more stable, and less are proven to be less likely to get into trouble in their personal lives later. it's the standard family time that is scheduled and are counted on. We do Dinner everynight and activities are scheduled around supper, no exceptions...even if suppertime is somewhat adjusted in time, we have a sit down supper everynight to re-connect with each other.
We also have Movie night and we all sit around and watch a movie, cuddle and eat popcorn with the surround sound and no lights. We do nothing else...even if I feel the need to do a load of laundry, I resist the urge. It's family night and that's that.
I've also heard of families that will choose a specific day for each child to spend at least 1 hour doing what they want. That way, each of their kids get some regular scheduled time to spend with mom/dad on his or her own.
You might need to get a sitter (or family member) to watch the others kids but in small incriments like an hour or so shouldn't be too hard. You might need to start out at 15 minutes each, or something like that until something solid is established and everyone gets used to a new reutine. You might even have to take the opportunity to do this while one of your kids is at soccer, etc...and you'll have some one-on-one time with another child. It's just a matter of fitting it in and making the choice in your head that it's a high priority.
Also, make time for yourself to get out and go for a walk, bikeride, get a haircut, etc. 15 minutes or a 1/2 hour can make a big difference.
