Differences in having 3 kids vs 4?

I wanted to ask those who had 2 kids and made the jump to 3, and even the ones who made the jump from 3 to 4, what would you say is the ideal number of kids. I know everyone is different, but wanted to get a gist of where folks' minds are at in either situation.

What is life like managing 3/4? I feel like 3 is perfect as it isn't TOO MANY, nor is to just the two siblings who have each other and thats it, I feel like a 3rd brings in variety and, just seems like it completes a family all-around.

With 4, I imagine it is challenging with being attentive and involved in each one's life compared to 3. Also, feel like going just about anywhere with 4 and it seems like you are moving a mini army! (grocery store, restaurants, traveling, visiting family etc) LOL.

3 seems like I can still control things and enjoy life whereas 4 makes me over-stimulated just thinking about it! 😂

Again this is just my opinion and there isn't any wrong answer.

What are your thoughts?
