Feed baby Theo

Theo has recently been diagnosed with GERD and a milk protein and soy allergy. I had to stop breastfeeding him at 10 weeks because he was no longer able to have my milk which was causing him extreme reflux and esophagitis even after trying eliminating dairy and soy. The only formula he can have is called puramino by nutrimagen, he's totally more healthy since he started using the samples from dr office. Unfortunately, even with the dr prescriptions our insurance won't cover the cost of our formula that is 1500$ a month for my little guy because he's not tube fed :( he can only have this formula to live healthy, others caused really really bad reflux and esophagitis as well as allergic reactions and so did my breastmilk. I'm a full time student and we are living on my husbands salary and 1500$ monthly is just so much for us right now but I'm ready to try anything to keep my little guy healthy!
