Three children are listed on the 1900 census. Zero children are listed on the 1880 census. It is not necessary for this unnamed child to be older than Belle, however it would seem likely he is older than Donaldson. Either he was born after the 1 Jun 1880 census & before Feb 1881, or he is a twin of Belle, or he was born between Jun 1882 & Jun 1883, or he is a twin of Donaldson.
