I hope you do look into the information offered, because I'm not so confident that your doctor knows what he's talking about. The La Leche League people or an experienced lactation consultant would have more options available to you because it's their area of expertise. Personally, I'm not sure that low allergy formula would actually solve your problem. I, myself, would be really mad if I switched my baby to formula unnecessarily on a doctor's recommendation. I really recommend calling someone with more expertise with special breastfeeding situations.
Just my two-cents worth...I hope everything gets settled down soon.
