Dear Lactation Consultant,
I have a 14-month-old who has had failure to thrive, blood in the stools, purple mottling and various other health problems. Jillian has recently been diagnosed as allergic to several things -- dairy, soy, corn, shellfish and another couple. I have been advised to wean. Anyway, here's my question. How long does it takes for a food to leave the system (breast milk wise) after I eat it -- for example, if I want shellfish, but Jillian can't have any, how long does it effect the milk?
