How do you know when you’re ready for another kid?

So I currently have a 2 year old and have been TTC but I sometimes get anxiety or overthink it sometimes. Like whenever I do get another baby I wonder if I’ll be able to do it I’m scared I’ll “fail” at being a mom to more than one child. Idk why I think that because I’m a great mother I LOVE being a mom so so much and cannot wait to do it again, but my anxiety gets to me. How did you know you were ready for another baby?
