The meaning of "tearing the intestines" is that the child becomes satiated from the milk.
The meaning of the hadith is that only that suckling (radā‘ah) is considered valid which occurs at an age when the child’s nourishment is the mother’s milk.
In normal circumstances, suckling an older child does not establish the relationship of suckling (radā‘ah).
