I also do a transition time while mom is still off work. Two weeks prior to start date I have the child come just for about two hours in the morning. Then the second time they come in the am and stay for lunch and the next time they stay for nap. Then the second week I have them dropped off at what ever will be the regular drop off time and stay for full days but mom is available just in case. Then we start full time. I have not had a child cry for more then a few days.
