How early is too early?

Amy • Mom to 4 beautiful girls. 3/3/10, 4/27/14, 4/8/17, 3/7/19.

My little girl just hit the 8 month mark, I’ve been going baby crazy and potentially wanting to try for another since she was like 3 months. If we do decide this would be our 4th kiddo. My other kids are pretty spaced out. I’ve got a 7 yr old, 3 yr old, and my 8 month old.
