What.....no dairy?!!!

Okay, so we've been having issues with Aidan for a while now regarding fussiness and congestion. He was to the point that he required someone holding him at all times (and even then that didn't always work) to put the crying at ease. Then he developed sniffles that never went away, & finally a rash on his torso, arms, legs. We went to the pediatrician 3 times in 2 weeks and finally (after sampling his poo...which has been very runny (but I thought that's how breastfed babies poos was suppose to be)) discovered that he has an intolerance to the protein in milk! What a relief to figure that out...but, I have to give up dairy if I want to continue breastfeeding! It has been 4+ days with success and we have a new baby on our hands...smiling & cooing; however, mommy is a little irritated. I never realized it...but, EVERYTHING has milk/dairy in it!!!!!!!!!!
Please send a prayer my way that I can keep this up; otherwise, we'll be switching to formula. The doc recommends Alimentum, which at our Kroger's cost us $25.99 for the smallest canister....can you believe that????????
