How do you know when you're ready for another baby?

Ly

My baby is 11 months old and I've had baby fever SO BAD the past 2 months. At times I really want another child and then other times I like how easy it is with what we have going and feel a second child would be more than I can handle right now. It's a mess really. Our first wasn't planned at all so how do you know when you're actually ready for #2?

We are financially ready and both agreed we'd be okay with another child. I just have random moments of doubts of taking care of 2 kids.
