Hi J.,
First of all, this is totally normal. This is the age for separation anxiety to be in full swing. This is a hard time and it's going to be a challenge for you and for the sitter. It's a lot to ask of a stranger, but just tip her well :-). The process is easier if you gradually increase the time you spend away from him. Even at home, if you put him in his playpen and leave the room for 2 minutes. Comfort him when you return, then increase to 3 minutes, then 5.. They are in the process of learning that mommy does come back. This is just a tough time to start leaving him.. but you have to do what you have to do.. You're going to have problems for a while but it is a stage, and all babies do go through it. You're not doing anything wrong by leaving him for short periods of time. I know it's hard for you and hard for the sitter, but you have to do what's right for you.
