Haven't done it yet, but both kids would probably be fairly comfortable with DH overnight at this point. DS (2.5) still nurses at bedtime and then at 6:30am in the morning so even if I did go somewhere overnight it would only be for 10 or 11 hours. DD did stay with friends of ours for 12 hours (~5am-~5pm, not overnight) while I was having DS and she was 2.5 at the time. I was only nursing her morning and bedtime at that point and she did fine skipping her morning nursing that day. I was prepared at that point to leave her overnight or even for several days if I had a c-section or something, though.
DD (5) hates it when I leave the house after bedtime, I think because she will not see me come home (since she'll be asleep). She asks every night before she goes to bed if anyone is leaving th house. Ever since my mother died suddenly a couple years ago DD sometimes gets really scared when DH or I leave. She has a lot of fears of us dying. So I could see DD being really anxious for me leaving for a weekend or something. Not that it would keep me from going, but it is a consideration. I've thought of going away for a night in a motel just to get a full night's sleep (DS still wakes a lot at night) but it just wouldn't be worth the hassle, anxiety for the kids, stress for DH, and expense just for 10 or 11 hours overnight away from the kids. Honestly I'd rather have 10 or 11 daytime hours away from them because I could get so much stuff done!
I would love to go away for a weekend (either alone or with DH) but with DS still nursing and no one to watch the kids anyway it just isn't going to happen anytime soon. My fantasy is that an awesome nanny comes on a vacation with us for a long weekend (and stays with the kids in a nearby room) and DH and I see the kids several hours a day. :)
Re: the original intent of this post, I know lots and lots of people IRL who have left young (<1 YO) babies for weekends or longer and while I never did it (no one to watch the kids and also I never had a pump) I wouldn't consider it weird or atypical. I wouldn't have done it with DD because I was more protective of her as my first and less in need of a break. But if circumstances had allowed I would have loved a weekend away from time to time starting when DS was about 9 or 10 months old (DD 3.5 YO at that point).
