I would have absolutely said stop at 2 a few years ago.
The early years were pretty good - it was hard work and I was very tired, thought that was just about alright and loved our little gang.
Then they grew up a bit and I was run ragged, stressed out, they were arguing, it was like herding cats. How I laughed at those naive fools on here saying that they had thought about the challenges of having a third or fourth - the need for a bigger car, the extra expense, whether or not the kids would have each have their own bedroom - as if these issues were the main things that would bring a parent to their knees! I was bottom of the list of my own priorities for a decade.
It’s the stress of managing the personal dynamics, the lack of time, energy, sleep, the parenting conflicts, the multiplying social issues/challenges/demands for each child that need attending to, the exponential rise in family relationships that require managing that fuelled the problems in our household. it’s possible that it was doubly horrendous because they and all their peers were struggling through the covid years leading to real issues and concerns within their social
groups.
They are now older and I'm currently glad we had more, especially as the older ones leave home. We’re in a good patch. I do however consider us very lucky to still be married, and we have paid out a lot - a lot! - on therapy. And depending on how anxious a person you are, having another child will add an extra person to be anxious about, and possibly have to provide support to, for the rest of your life.
