I was 27 when I had my lst child, my son. And I was 30 when I had my daughter. I can remember when my DH & I brought our son home from the hospital. I thought, even at age 27, my god, we are actually the caregivers of this dear sweet boy and I don't know a thing.
But you learn as you go. I read some books and asked lots of questions of my mom and sisters who allready had children. I was lucky. I had 4 months off with each of my children before I went back to work. But I worked at the same place both times and they were very generous with my time off.
It wasn't paid time off though.
