The staying put is my reason for the lay down first and rest and I will come back for you - I need to know that I have a specific amount of time to do what I need to do and then I am ready to interact with the child too. It is more of a mental break for me as I really don't care if a child is up while I eat my lunch but I want to be able to not have to think about what they are doing. I vary the length of time I go back for the child on how their behaviour was all morning, how busy our morning was, how long it takes me to do what I had planned for naptime, etc.
