DS (19 months) has been eating cheese, yoghurt and small amounts of cows milk for ages, but has been breast fed and never had much cows milk as an actual drink. I have started to wean him and he's finally started accepting cows milk, but now has foul runny poos. Has anyone else experienced this in a child who has had no dramas with other dairy products? Is it likely to go away as his tummy gets used to it? Or would you think he has a dairy intolerance. Apart from the frequent runny poos, he seems completely fine.
