The cost of a
consult with a
lactation consultant is far less than the cost of formula and the likely increase in healthcare costs
later in life, so hiring a private practice
lactation consultant to work for you alone may be your best bet.
There are many reasons why a woman might have low milk supply and I think it IS important to state (like Ariella mentions in a
later comment) that if you are having supply issue you should
consult with a
lactation consultant and / or physician.
