I know lactose intolerance is rare in infants (and caucasians), but I think my baby might actually be one of the few. He was in the NICU for 2 weeks due to not breathing at birth, so at first he was fed lipids etc. through an IV. Then he was given pumped bm through gavage and then through bottle, then we nursed. I noticed right away that he pooped alot - I would change a poopy diaper before a meal and after a meal, and sometimes during the meal. The nurses were a little surprised, but no body thought anything of it. When I brought him home, he continued having all those stools. They raised their eyebrows at the ped. but said nothing about it. Shortly after I brought him home, he started fussing about nursing and started to refuse to nurse. I chocked it up to nipple confusion since I had to supplement with bottles due to low milk supply, and eventually decided to just bottlefeed because we were both too distressed. Then he started refusing to bottlefeed. He was extremely colicky at feeds - arched back after a few minutes and started screaming and would refuse to continue. So I changed him to Alimentum - which I understand is lactose free but still cow's milk based so still has the proteins but they are predigested - and started freezing the pumped bm so I could try to narrow things down. The Alimentum worked almost immediately. Today I have a cold and wanted him to get the immunities, so I tried to add back some bm with his formula, and he started colicking within just a few minutes and would not finish his bottle, and then was hard to settle afterwards. Doesn't that sound like lactose is the problem? I guess it could be because I have cow's milk proteins in my milk that are not predigested... Just trying to see if I can pin it on lactose or not, cause there are lactose free formulas that are much cheaper than Alimentum... Any insights?
