My ds is 15 months and been on a dairy free diet from Birth, He eats lots of vegs and pulses such as beans and lentils I buy dairy free spread so he can have toast and sandwiches. I am vegetarian and so are my other kids alot of the quorn stuff still contains milk so be careful with that, the realeat stuff is what I use as it has no dairy you can buy from health shops. Yoghurt I buy alpro soya and for little treats he has organix carrots sticks and dairy free buttons.
Ds was under dietitian but wasn't much help at all x
