I found three to be a horror show. Maybe because kid #2 was like having four in one. But then, I pretty much had them by myself most of the time.
I also didn't overschedule anyone. If it was going to be a logistical nightmare to get a kid to dance class, they didn't sign up for it. And I couldn't afford it anyway, LOL.
As soon as they're old enough, get them to do stuff around the house. Mine started doing their own laundry at about 8. Sounds harsh, but they didn't appreciate my efforts and I was always crabbing about clean clothes on the floor, etc.
They could all cook themselves something halfway decent by about twelve or so.
We really had no thought about "quality time". We spent a lot of time together (see above re: overscheduling) as a group.
Depending on the ages of the kids, having enough room in your car for three car seats could be a problem. And finding a sitter was really hard.
School lunch money sucked. $2.75/ kid. So I gotta come up with six dollar bills and nine quarters every day? PITA.
Grocery shopping was h-e-double hockey sticks, but not as bad as clothes shopping with three kids.
Good Luck!
