How do you make it work with 4 or more kids?

I want between 5-6 kids and hubby wants between 3-4 (preferably 3). He thinks that it will be hard to handle any more because of different schedules if they’re in extracurricular activities or sports and us working and the possibility of them not getting along.

He is the oldest of 5 siblings, most of which don’t get along. I understand his worries about them not getting along but I am the oldest of 3, pretty much 4, and know that growing up there is always a stage in the pre-teen/teen years where siblings tend to fight a lot. Me and my siblings are all super close now, whereas my SO’s are not.

His mother also had a hard time going to all of their sports events because she was a single mom so some kids felt left out or felt others were favored over them. I do see where his worry stems from, but I feel like if we are hands on (and that there are 2 of us) and raise well-behaved kids it shouldn’t be a problem.

We want to start growing our family in he next couple years and want all the kids really close in age (14-18 mo apart). So my thing is if they’re all close in age, theres a possibility that they’d be in the same sports or within the same area where one of us could be at an event for them, and there’s always the possibility that they don’t want to be in anything which is fine too.

I guess I’m just wondering how parents of more than 4 kids make it work? What is your schedule like? Do you think you should have stopped at less kids (don’t get me wrong, I’m sure you love them)? Do they get along? How close in age are they? Any advice at all??

Thanks in advance!
