A.N.
You're not crazy, you're a mom! Something happens to us when we become mothers. Sometimes, we become a new, different person than what we thought we were. I was raised to be very independent. Before I met my husband, I had a career, car, mortgage, graduate-school education, etc. I always knew that I would return to work after having children, and the idea of daycare never phased me. Here I am a few years later as a stay at home mom! I returned to work after my maternity leave and felt much the same way as you do now. I left my job after a few months back. I just couldn't find the balance I was hoping for. That's not to say that either road is better than the other (working mom or SAHM). I'm just saying that each family's situation is unique, and you just have to listen to your heart as to what is right for yours logistically, financially, emotionally, etc.
Naturally, it is difficult to leave your infant with a stranger. I think your feelings are completely normal. However, it does get easier to leave them over time. I would encourage you to get to know your daycare providers personally and comfort yourself with facts about the facility's safety measures, curriculum, activities, etc. If you are confident that your child is in a safe, loving environment, it does get easier. Good luck to you!
