My MIL is coming from abroad (US) to stay with us next week. She doesn't fly alone, so she's meeting my OH when he's on a business trip, and flying back with him. This is the first time she's meeting DS, and she's staying with us. I'm flying back to the US early for the holidays to be with my family and taking DS with me (on the 10th) and my OH is following on the (22nd). She wants to stay with my OH after DS and I leave. I'm a bit weirded out by it and uncomfortable. Is that wrong? I'd rather she fly back with DS and I.
