Hi there,
I too want to introduce tofu to my DD but wasn't sure when to do it (shes 6 months and 1 week old). Its a good high protein meat alternative (we are vegetarian) and is supposed to have alot of iron, potassium and calcium. The Annabel Karmel recipe book suggests mixing it with banana: 1 small ripe banana + 50g (2 oz) soft tofu. She also says you can mix it with mango or peaches.
HTH
