His issues started after a month of being on Nutramigen. And Now I know why. Milk
has 2 main protiens, Casien and Lactose
is a secondary sugar protien. Lactose is usually what most intolerant babies can't handle, not the casien. Lactose hits the body almost immediately after drinking it while casien takes a while to build up in the system.
Now the spitting up, fussiness, diarreah, rash, projectile vommiting didnt start until a month of being on Nutramigen.
