Because if you start trying to tell a mother that there are behaviour issues and start telling them however nicely you try to word it that they need to change what they are doing at home (amounts to telling them they are parenting wrong even if said overly sweetly or discretely) then the parents get their back up and a great percent of the time the parents pull the child from your care because if there are issues it must be the caregiver that isn't good enough because afterall their child is perfect and their parenting is perfect.
