Did you have a 2nd kid after deliberating long and hard? OR decide to stay OAD? How did it go?

I'm really struggling with the decision as to whether we should try for a 2nd kid, and am so grateful to have found this community -- so much so that I am posting on reddit for the first time ever.

I feel genuinely ambivalent about the prospect of a second kid -- there are days where I feel totally certain in both directions -- and I don't encounter anyone in my non-internet life who is similarly confused. I love being a mom to my almost 3 y/o and am fortunate to have a supportive community around me -- but I fear disrupting the lovely equilibrium of our current situation, and a second pregnancy/kid feels like a spectacular dice roll in many ways.

I would love to hear from parents who made a decision one way or another after deliberating for a long time. How did it go? Anything you wish you'd known or thought about prior to making this decision?
