It was me that mentioned day care workers. Your child doesn't need to attend, you could ask at a local centre if any of the workers do babysitting also. At Jack's centre nearly every carer does sitting. We used Jack's carer one night. She was brilliant and only charged $12 / hour which seemed reasonable for a qualified, experienced carer. It was a huge bonus for me that I also knew her quite well and Jack also knows and loves her so was happy to stay with her. But even if you don't know the carer before hand, you might feel more comfortable with a day care worker rather than an agency sitter.

DH and I also need to get out together occaissonally in order to maintain our relationship and I think this is vitally important. I totally understand where you are coming from Tegan, and I recommend you get a sitter and go out. It will do you the world of good, and happy parents make for happy kids. Good luck sweetie.
