I do very similar as Lee Bee if it is an infant starting. At least 3 visits the week before care starts in increasing length each day. I do it at an hourly rate of $10/hr and once they reach 3 hrs or stay for lunch or nap, then it's the full day rate. It's up to you what you see fit to charge depnding on how long they are visiting. For the older ones, I usually do 1-2 visits before starting.
