How did you decide when to have a second baby? Did you base it on a desired age difference? Did you wait until baby #1 was a certain age? Did you wait until you felt "ready" to go through it all again?
Even though LO is only 5 months old, I'm starting to think about baby#2. My mom says that she could have waited a couple of more years before having me (I'm #2) but didn't want to have a big age gap with my brother so they just decided to go for it.
How did you decide?
