Aptamil Comfort is suitable from birth onwards. As it is a nutritionally complete formula, your baby can stay on Aptamil Comfort until they are 12 months old - use it as part of their weaning diet from 6 months. If your baby has been diagnosed with colic or constipation by a doctor, switching to Aptamil Comfort can be done quickly to allow them to benefit from its gentler formula as soon as possible.
