DS is 6 1/2 months old and weaning is going well.
He seems to not be able to process yogourt or fromage frais (plain or with fruits) as he will vomit it soon after eating it.
He does have full fat milk with his cereals and is FF since birth so I suppose that he is not intolerant to lactose 
Is that normal that the yogourt is a no go at that age? Or what can be the problem?
Thanks for your thoughts
