I offer the parents the option of transition days just for the simple fact that it makes the parents feel a bit better about their child starting daycare, and for the child to get used to being away from their parents. All the children I have taken into care had not been away from their parents very much so it allows both to get used to not being with each other before they start care. However, I normally do it the week before care starts so there really isn't a break in between the days. I normally do like a Wed-Thurs-Fri then start care on the Monday type thing. I do think it is more for the parents then the child, but so far, all the children have taken the separation/transition pretty well. I'm about to start two new kids next month and I am offering transition days.
