TTC #2 and Pregnancy Spacing Advice

Hi everyone, I’m new to the Glow Community and looking for advice from mommas with 2 under 2. My husband and I have a 9 month old son and recently started discussing TTC baby #2. This month was our first month without using protection (condoms) and I haven’t been on birth control. I’m feeling a little nervous about this after reading about certain risk factors with pregnancies spaced close together. I was looking for some advice from other moms who have children close in age and particularly how their 2nd pregnancy was? Thank you!
