Test weights with a sensitive scale can be excellent tools. As with any tool, scales/weights should be used judiciously. To verify that a baby has in fact taken in milk at breast is one use; to verify that the baby has NOT effectively taken milk is just as important in some situations. Mums can be overconfident or under-confident - a good scale can wake up the overconfident, and reassure the under-confident.
