What do you think of "those" parents?

by “those” i mean, the ones who childproof their entire house, spray disinfectant all over their kids and dont let their child play near the sandbox.

personally, i am opposed to this, because pain teaches us a lesson. if you touch a hot stove and you get hurt, chances are you wont touch it again because you know it will hurt you. antibacterial soaps limit the immune system and dont prepare the body for a fight against diseases. when kids play in mud, they ingest bacteria, and hopefully the child beats the sickness associated with it. after that, he or she will be immune.

this leads to the discussion of parents who refuse to immunize their kids because its unnatural. what are your thoughts?
