When it comes to my dc I don't coddle my kids. If they cry I don't run to them unless someone really gets hurt, but if it because they don't want to sleep or someone took their toy. I just let them work it out them self.
I am the same way. They are my clients NOT my kids. I feel that I would be disrespecting my children if I "loved" the daycare kids. I do like the kids in my care, but no hugs or kisses from me, those are for my kids.

If a parent wants someone to love their kids then maybe they should take the time to do it. JMO
