It can definitely be done, you just have to have determination and a good support system. I found out I was pregnant with my first child the first month I was in grad school. Seven months after having the baby I found out we were pregnant again. I finished the ACNP program in under 3 years and kept a really good GPA. Granted, I was able to quit working as a RN before I delivered the first, and have a very supportive husband. Just know that it will be difficult but the rewards of being a parent are worth it. Good luck!
