Next week I'm going on a work conference for four days in France. Quite looking forward to it in a way, but dreading leaving dd. I'm really going to miss her, and get depressed just thinking about it. DD is 14 months and dh will be with her, and my in-laws are coming to stay. My parents only live a few miles away too so she's not going to be short of family, but it's the first time I've ever left her. Any advice/words of comfort?
