When the nursery becomes "difficult"

My two year old daughter had a little trouble at some point during the separation in the morning at the nursery. This book could put words to his malaise and make him a clear message and imaged suitable for their age, something with my simple words I could not make him understand. Namely, I put you in the morning but do not bother in the evening I come back and get you whatever happens, I will not forget you. The fact that there is a father and a mother in the story makes the thing adaptable to all situations. In addition, the book traces the whole "normal" day at the nursery, which helps smaller to more easily identify.
