Interested to know what people opinions of this are: SD staying at ours for a week, we have been invited out by another couple for dinner so we would require getting a babysitter for her and our other 2 kids. Is this ok? Or should we put it off until SD has gone home? My DH said it seems unfair as it's meant to be his time to see her and he will be working all week so only be home in evenings. Thanks
