I keep saying this because I keep seeing the same situation coming up over and over lately: Toddlers do not belong around any rooster because of the way young kids move. They make sudden and jerky movements and make roosters nervous. Think of them as a stallion or bull in a smaller package. I wouldn't even allow my very docile, calm, non-human-aggressive roosters around small children because it only takes one time for a child to lose his eyesight from a rooster attack, just once.
It doesn't matter if you raise a rooster from a chick. Some are just going to be human aggressive--it's an inherited trait and will pass down from sire to progeny if you keep breeding a human aggressive rooster. Sometimes, the friendliest cockerels as youngsters turn out to be the most aggressive--they see you as someone they are on even par with and they will take you on if you have babied them up till their hormones begin to rage, if it's in their nature already to be that way. BUT, even a non human aggressive rooster will not react the same around a loud, overactive toddler that he will around an adult most of the time.
I saw it this weekend with my own very sweet rooster, Isaac, in my avatar. He adores me. I can get up in his face, mess with his wattles and comb, scratch his chest, call him and he comes running, but the neighbor's grandkids were screaming and making all sorts of noise about 300 ft away through the trees and he was extremely nervous at all their kid noise.
