I dont do interviews during daycare hours for security reasons and I generally do a bit of transitioning and have the parents drop off for an hour in the am the first day and then two hours the second day and then for lunch the next day and progressively longer. I'm most interested in getting a nap out of them before the parent starts back to work. This all depends on the time frame available and he age of the child ..... If I'm dealing with a child that has been in care before then I just do one or two visits .... I try to do more if its a parent coming off mat leave. If its good weather and the parent wants to stay for 15 mins or so then I have them come when we are outside.
