Once you have got rid of the youghurt, I used to buy DS2 a soy yoghurt King Land Soy Yoghurt in the mulit packs. He loved it. It's availalbe in Coles in the fridge part near where the cheeses are usually. They have Soy Life yoghurt as well, he preferred the Kind Land.
i also made a soy custard for him as well which he liked. You can make polenta fingers using soy milk with a little bit of vanilla essence they are really yummy.
Thanks hun, i might have to look at that, the only issue is we don't knwo what exactly caused her reaction, i'm not sure it's dairy as i have a lot of milk and cheese and she doesn't seem to be getting anything through my BM or reacting, it was the first time she had had yoghurt so i just don't know, hopefully RCH call me soon about an appt.. no new foods til then.. for her or me!
