Norm here too.
DCF brings their child 3 days per week, sometimes asks for more if they have things to do that would be easier done with the child - appointments or shopping kinda thing.
I guess I don't mind, since if they had pulled their child, then I would of had to find another family (and this family is very good, so I would hate to loose them!), which I didn't have to do in this case and soon enough I will be getting the little one too!
I also have a DCF only has one child and if they get off early or have a day off they spend it alone...spa day is what DCM has told me! I've had DCD from the same family drive past me while picking up kids from the school, so I know he is home, but he shows up on the button at closing...says he went to have a nap or start dinner!? It really floors me to be honest. I worked after I had my son and any day I could leave early to get him I would in a heart beat! It's kinda sad actually...
