I'm 26 with a 14 month old. My dream is always to have a big family of 4 kids. Everyone keeps saying that if I want a big family I have hurry up and try for another baby now but we're not ready for another baby yet and would like to spread out pregnancies around 3.5 years apart. I work a full time job and depend on maternity leave so I cannot keep taking maternity leave back to back. And it would be nice to have a child that can go to a pre-K program and is out of diapers by the time I have a newborn. So in this case I know I will be TTC in my 30s for my last 2 kids (if God's or universe's willing).
