Going back to work

I start back to work part time on Monday. I'm so nervous about leaving my little one. She doesn't do good with a bottle. The only one we can get her to even tolerate is the playtex drop in. She really doesn't even like that one. I have tried so many. I just got the comotomo and Dr. brown in the mail today. So we will try those. I just hate thinking that she will be crying and hungry while I'm gone, and I feel sorry for my mom and MIL who will be watching her while I'm gone.
