Mine will be 3 and almost 2 when #3 comes. So I packed them in. But i wanted them to be able to enjoy the same experiences growing up, not have one be the baby that just gets dragged around to whatever the big kids are doing / enjoy at that age. And I want to be able to do some active family trips and summer experiences when they're all in that sweet spot of not being little kids but also not totally over family time yet. Not a judgment against biggest spacing, there are merits to that too, just how I viewed it
