1/2) I tell parents at interview time that that if they would like the spot the have to email me (i like to have things in writing) by XX time on XX date and that the following day I will make my decision and starting calling family's I would like. I let them know that if they do not email mail me then I will just assume they do not want the spot.
3) Interview all family's you have scheduled. You never know you might find a even better family. this happened to me. I found a good family the next day did another interview and found an even better fit. but you do have 3 spots so signing on one before the deadline might be ok.
4)I don't hand out my handbook or contract until they have signed on. you will just waste a lot of paper. I have posted all the information and copies of my contracts on my website I just tell them to go and look at them there.
5) I ask parents if they would like to asks questions first or have me go through everything then ask questions. this works for me.
6) kids should nap in a safe room, that you are comfortable having them in. Make sure you can check on them easily. The kid I watch started out sleeping on my living room floor and now are in my boys room. you might find that your son wants to nap with the other kids in that case the play room would work fine.
