Hi I am a single father of a 9 months old child. My kid has just started crawling and it is quit difficult for me to handle him as he is a very restless child. At times I cannot pay attention to what he is picking up and putting in his mouth. Therefore I am really scared about the moth balls kept in the house, is it fatal to even sniff it for longer period? I want to know the moth balls danger and is it safe to keep it at home when you have a child?
