My bb also lactose intolerance and he spits milk easily since birth so he has to drink special formula ie Enfamil AR, but still sometimes he will spit and he cant drink normal Enfamil A+
My baby was very windy and we tried Infocal on him first then he passed lots of wind but still unsettled with crying and tummy pains and we thought he was lactose intolerance. The doctor then prescribed Colief for him but on a much lighter dose than what is suggested on the package (only 1 drop for 3 times a day) and he changed to a thicker formula milk as well.
My experience is that Colief 'seems' to work initially (for the first couple of days) but no difference afterwards and I stopped using it gradually. But I think when we have a colicy baby, we keep trying different things, time passes and colic disappears gradually when the baby's digestive system matures (when they are 3-4 months old)...
If you want to try, try it for one week and if it doesn't show any improvements, go back to normal feed ~ according to some NHS advice I heard over here.
the reason i want to try colief or infocal becos i want to drink normal formula as the ingredients are different from Enfamil AR but I gave him Enfamil A+ but he spits immediately after he finished his bottle, so doctor suggested not to change formula until he reaches 6 months
