@ meags, I remember reading an article saying that the hypoallergenic dairy formulas are tolerated by about 90% of babies with dairy allergies because the cows milk protein (the coes milk protein that is usually the cause of the problem) has been partially hydrgenised...... have you tried one of the HA varients available in the UK?
BTW I just thought I'd jump in here (because I used to make this mistake) human milk has one of the highest concentrations of lactase compared with other mammals. Most people who are dairy intolerant are so because of the casein in cows milk - which goats milk doesnt have (or does in much lower quantities), which is why people who are cows milk intolerant, can often use it....
Lactose or milk sugar intolerance is not commonly observed in infants The lactase enzyme reaches its maximum level in the human intestine soon after birth and declines after age 3 1/2, so symptoms of insufficient lactase may not begin to show up until after this age.
If their is a true lactodse intolerance (and symptoms of cows milk protein and lactose intolerance are the same) you could also supplement with lactase drops (a few drops before each feed). I dont know where you would get them in the US, but I know that Dischem sells it in SA:)
True lactose intolerance in babies is actually quite rare, but often be cutting lactose out of the diet, lactase (the enzyme used to digest lctose) is reduced and a secondary lactose intolerance can result.
Just a question Meags....Do you think thats why you had issues with breastfeeding - I know you had to toss out your pumped suppy, Do you think either the dairy you were eating/or the lactose in your milk was upsetting and hurting his tummy making it sore to eat?????? Shame poor baby, you've really been having a hard time:(
