If you are formula feeding, just switch the formula to lactose free Enfamil and it will clear up in less than 24 hours. (My son had this problem and changing the formula worked well, my dr. (not his ped) told me about this)
If you ask your ped they will said that it will pass in 3 months, but that is a little nuts. Drs in Europe are farther ahead on this problem than the ones in Canada and in the US.
Also, you can try biogaia probiotic drops, they have them at ShopersDrug Mart (ask the Pharmasist) or at a healthfood store in the fridge section. They might help.
