first days of work

Well I started working this week, on Monday and Tuesday I went in for orientation finished that all up and I am starting really working on Monday. I am really excited that I am actually getting to use all of the knowledge that I acquired while in nursing school....and I actually remembered it. During orientation I had to take 2 tests that tested on the medications and dosages and all of that kind of stuff...and I made a 95 on both of them! I was rather shocked because I felt like I didn't remember any of it. Braden however isn't liking me working at ALL. Monday I just wore street clothes to work because we were just watching videos all day, but yesterday I wore my scrubs and I didn't have to be there until 9. So I walked into the living room to get him ready to go and he said "mommy...are you a nurse today?" me: "yes, I have to go to work today and be a nurse" braden: "but i don't want you to be a nurse, I want you to be my mommy..." and he started crying. I feel so bad for the little guy, we have been at home together since June, and he has just gotten used to spending all of his time with me. He didn't even go to his BSF Bible School this morning, he just starting crying saying "i don't want to go anywhere, I want to stay here with you." Hopefully he will adjust soon....I really don't like it when he is upset.
