I did the Fenugreek and noticed a difference within a day. I would think that these would be similar. The maple syrup isn't actually a bad thing, except that you want pancakes all the time. :) And I never noticed baby to have the smell, just me (sweat, urine).
I know that with the Fenugreek, they say to ignore the label and start with 3, 3 times a day, and increase up to 5-6, 3 times a day. I'm not sure what those pills say, but you may want to ask a lactation consultant if you don't notice a difference soon.
