Pros and cons for #2?

I have an almost 3 year old, me and my husband have been back and forth about trying for #2. I’m on the pill and I’ve been on it since I had my daughter. Pros and cons of having a baby and a toddler?? I’m a little scared but I kinda wanna do it?? And I also don’t even know how long it would take if I got off my birth control in the next couple of weeks.
