About a month ago I put ds1 onto a dairy free diet, and he has since lost a lot of weight (and was pretty small to begin with). He was eating lots of yoghurt and cheese, but won't touch the dairy free alternatives.
He is not an adventurous eater and won't eat potatoes or vegetables (except the occasional pea). HV told me to give him crisps on the grounds that they're potatoes.
I've made some dairy free cakes and pancakes, but need other ideas.
