How did you know you were ready for a third child?

This has been popping up in my head a lot lately, especially since my boyfriend told me we can start trying after we're married. He said he's planning on getting me an engagement ring within the next few months and a wedding wouldn't be far off from that.

But my main concern is juggling 3 kids. My girl is 4, my boy is almost 3. We're just now out of the "pull-ups" stage and I'm not excited about the prospect of more diapers and no sleep. 😂

But I do miss the baby snuggles. The smell of newborn and the "first" everything.

I'm just curious if the realization hit you like a ton of bricks one day or you just kinda left it up to a higher power or what have you. Any input is appreciated.
