I think using one word to describe a child's personality and temperament is lazy and stereotyping. All children are different - and having one characteristic (such as boisterousness - which I interpret as full of energy that need to be physically expended, a high level of physicality) doesn't preclude them having others.
I have known children who are bositerous, but kind and sensitive to others needs, I have known quiet calm children who are kind loving and thoughtful. I have also known children who are boisterous and unkind or rough, and quiet children who are unkind and mean. And every variation and combination in between.
With young children I find it is best to deal with poor behaviour on an incident by incident basis, and then move on, rather than typecast a child into a box called 'boisterous' or 'quiet' which they are then trapped in, so that all their behaviour is classified according to the descriptive boundary you have placed on them.
Just like adults, children are capable of a wide range of behaviours and have complex and individual personalities.
Any one who uses descriptor as code to stereotype and be unpleasant about a young child needs to have a rethink IMO.
A great deal of poor behaviour in children can be accounted for by adults inability to deal with it constructively and efficiently, rather than any inbuilt trait the child may have.
