As Gennadiy already said, if you want to use shared_ptr to manage memory, do
not use ordinary pointers.

void AddFooObject(shared_ptr<Foo> const & pFoo)
{
    m_vecChildren.push_back(pFoo);
}

If you want to avoid memory-related problems, never use an ordinary pointer
to hold memory allocated with "new".

shared_ptr<Foo> pFoo(new Foo());
