Our formula (Pure Goat Company's stage 1, 2 and 3) contains lactose (milk sugar). As a result, our products are not suitable for babies/children with a known lactose intolerance. Fortunately, lactose intolerance in babies is very rare. It is much more likely that intestinal discomfort is caused by something other than lactose intolerance. Or that it concerns intestinal cramps that are part of the growth and development of a baby; quite a lot changes in a very short time. If there is no cow's milk allergy, you can try follow-on milk based on goat's milk. Do check with your doctor or consultation office first
