I was in nursing school and working full-time when I found out I was pregnant with my first. Everyone advised me to stay in school or I wouldn't go back. I was so sick throughout my first two trimesters that I struggled. I finished the semester, then took the next semester off. I have not gone back...
When you see that little one, you will want to spend every minute with him/her. I worked full-time until my daughter was almost 2. My husband and I made the decision for me to resign from my full-time position and be an at-home mother. I have loved every minute of it and am now expecting #3.
I do not regret spending the time with my little ones and watching them grow. I do regret not finishing school. There is a sense of accomplishment that comes with finishing - and I don't have that. Nursing was my dream. It still is. But my kids are my focus right now. I'll get to chase my dream again someday, but I will likely have to start all over by the time that rolls around...
The best advice I had when I was pregnant - Finish now and when the baby's born, just get your schooling done. They won't remember daycare when they're so little, but if you are absent from their school play or chorus concert because you're in school, they will remember that...
You are NOT a failure if you quit! You just have to decide what your priorities are. Think about how you will be impacted financially if you don't finish school too. And just keep in mind that if you choose to postpone your education, your dream will just have to sit on the back burner for a bit. If you're okay with that, take a semester off. If not, press on!
Best wishes to you and congratulations on your little one!
