My son is 23 months old. My husband is a horse vet and occasionally, we find ourself hanging around the barn/hospital. One day, one of the workers was driving a tractor, which ds found to be the most exciting event he had seen all week, so we hung around to watch. The worker pulled over and asked ds if he's like to see the wheels or the levers or whatever. Ds looked up, thought a minute, and burst into hyterical tears and wanted to be picked up. This is VERY unlike him. He has never been afraid of anyone before (maybe a little hesitant, but warms up fast when he gets a smile). I KNOW nothing has happened to him, with this man or any other (I am a SAHM. I am with him ALL THE TIME. We have never left him with a babysitter-except my mom once when I went to the dentist, he has never shown any other signs of being afraid or distraught. I know this child in-and-out and can account for every minute of his life and this fear is out of the blue. This is TOTALLY RANDOM). Now, he is terrified of this worker. If we happen to glimpse him, ds starts crying and saying "Bye Bye!" and running to the door. I don't force anything, and the worker is nice about it, but the situation is a bit concerning and a touch embarassing. The best that I can come up with is that the worker was wearing sunglasses, a cowboy hat and has a mustache, which I know can be a bit scary for a toddler, but ds has never shown any fear of these things before, though he has not seen them all on the same person. Anyone else have a toddler who has a random fear of a person and/or suggestions as to why this is happening and what to do about it?
