I think what you're missing here is the fact that for Cranberry juice to work it has to be the UNSWEETENED version. Most cranberry juice we are all talking about how great it tastes (cause I like it too) is a cocktail and sweetened. Straight, unsweetened cranberry juice can be hard to get down.
OldFashioned ~ I also eat as many blueberries as I can get my hands on. This helps alleviate how much cranberry juice I need to drink. Also sometimes flushing with water can be enough to rid the body of the bacteria.... this means drinking so much water you feel like you will drown in it! And when all else fails, I find colloidal silver works wonders on everything we've ever contracted. I just like to try other things before relying on this alllll the time. Hope that helps. (And yes, it's safe for not only nursing mothers, but pregnant mothers and babies as well.)
OH yes, forgot to mention Nettles for UT issues including breaking down/dissolving kidney stones (helps with female issues as well). Great infusion, safe for nursing mothers, etc. Has a woody flavor but my 16 year and I love it. My 15 year could do without it altogether and the youngest two girls 12 and 7 will drink it without a lot of hoopla like the 15 year old but they'd rather not drink it at all... we drink it unsweetened or sweetened with stevia leaves. Haven't given any to the boys to know how they like it.
