DS was quite refluxy as a small baby, grew out of it at 5 months without needing medication. Sometimes fills nappy up to 6 times a day, other times can only be once. Doesn't seem constipated or diahorrea. Wakes up to 6 times a night still, quite windy and uncomfortable. Breastfed but has formula in porridge. No eczema, great weight gain. If dairy intolerant would he have other obvious symptoms?
