How far apart are your babies?!

We just had baby #1 about 4.5 weeks ago. We’re not in a hurry to have #2 per se, just looking at a good time frame to distance them and start trying again. I’ve heard 18 month gap between is rough because you have 2 “babies”. I’ve heard that 2 years is nice but still rough if #1 isn’t potty trained. And then I’ve heard 3-3.5 is nice cause they can help but are a little more independent. 3 years seems like a large gap to me. SO: how far apart are your babies? Do you like the gap? Why or why not? What would you change it to, if you’d change it. Thanks in advance!!
