Re: Is it too late?
Weaning from formula is absolutely possible. This link explains how to go about it: http://kellymom.com/bf/got-milk/basi...rease-formula/. Basically you increase the number of nursing sessions as much as possible while gradually cutting down on the amount of formula you're offering.
Fenugreek dosage is usually around 2-4 capsules 3 times a day, or enough that your sweat and urine start to smell like maple syrup (yes, really!). While fenugreek is helpful, do not expect it to do the job on it's own. When it comes to increasing supply, there is no substitute for increased frequency of stimulation to the breast via nursing or pumping.
