Start with a small tea spoon full and see if he likes it, and like any new food start slowly and gradually watching for any possible upsets as you go and remember to try and introduce only one new food at a time, a bit like a baby really.
I give mine Natural Organic Bio Yogurt with "all the good bacteria for healthy tums and digestive systems" a tablespoon twice a week on top of a little mashed banana, it's my breakfast and theirs also!
Rice and pasta are enjoyed by mine as well.
Remember not to give cakes and biscuits!!! and all the naughty things!!!
