1 Thessalonians 2:7 - Albert Barnes' Notes on the Bible

But we were gentle among you - Instead of using authority, we used only the most kind and gentle methods to win you and to promote your peace and order. The word here rendered “nurse,” may mean any one who nurses a child, whether a mother or another person. It seems here to refer to a mother (compare 1 Thessalonians 2:11), and the idea is, that the apostle felt for them the affectionate solicitude which a mother does for the child at her breast.
