Sounds about right. Let me say this: Breast milk is the VERY BEST thing a baby can have for many months after birth. There is NOTHING on earth that can compare to it. In addition to nourishing the baby with wonderfully nutritious milk, the mother provides the immune system to the baby by transferring her immune defenses directly to the baby when it feeds. This is mysterious, sacred, and shows God's love for us that He devised such a wonderful means to propagate his highest creation: Man.
$130,000 a month? Yeah, seems about right.
