She became very upset over that. Just today she collapsed in a fit of tears while I was washing broccoli in the sink. Your help would be greatly appreciated. I would suggest you consult with a professional who could make an accurate diagnosis. In the meantime, let me give you some information that might be helpful in understanding childhood fears and phobias.
All children have fears, to one degree or another.
This is especially true of young children up to the age of five or six years. The reason is that developmentally they do not fully understand the difference between fantasy and reality. Therefore, if the toothbrush or broccoli can go down the drain, in her mind, so could she or you. The difference between a normal fear and a phobia is the severity of the problem. Most parents are able to coax children to approach a feared object, praise them for their efforts, and demonstrate that the fear is unnecessary.
