So I've been stuck babysitting SD all weekend. Husband worked 12 hours yesterday and today is shaping up to be the same or more. 
We're supposed to have SD every weekend (no CO, just what they agreed upon). Lately, however, we've had at least 5 days out of the week.  Since she just went back to BM's on Wednesday night, she asked if it was okay to stay there this weekend. DH told her it was fine, but BM told her no way, she had plans.
