It is important to remember that some birds are very frightened of children. The primary reason for this fear arises from the quick and jerky movements of children compared with adults. Children also tend to be louder and more boisterous than adults. Bearing in mind that humans are essentially seen by birds as predators, children, even though they are much smaller, are seen as very dangerous creatures.
It is also extremely important to consider the danger that a large parrot may pose to a small child. Tiny fingers can be severely injured and it can happen very quickly, even when the bird may be confined to a cage or aviary. If you choose to make a parrot part of a family that includes young children, the onus is on the parent to ensure that both the bird and the children are safe. This is doubly important for things like play dates when the friends of your children may be visiting. You must not allow the playmates of your children to torment or annoy your parrot or allow them to be bitten and maimed. All members of your family must learn consideration and respect for your avian companion.
One last consideration if your children handle large parrots.... Although your bird(s) may have been domestically raised and seemingly very tame, they are still wild animals. They are not domesticated in the same way that cats or dogs have become. As such, they can at times be very unpredictable. In a split second, a loving and friendly parrot can bite even their most beloved human companion. These bites can occur any place on your body, including the face. An adult has the knowledge and can accept the risk of potentially catastrophic bites to the face that could result not only in a painful injury but also potentially lifelong maiming. Children cannot and should not be subjected to this risk. Please consider that before you allow your children to handle a large parrot, especially without direct, hands on supervision.
