I gave birth to my first just past my 38th birthday. We wanted two and due to age, and with my OB’s blessing, we started trying 6 months pp. It took 7 cycles and 1 miscarriage before I gave birth to my second just before I turned 40.
For us, we knew we wanted a second baby and that time was not on our side. At that age, you just don’t know what your fertility will be so we wanted to get trying as soon as possible. Having the babies so close together (20 months) isn’t easy, but it was so cute and so worth it. They are now 7 and 5.5.
