DS doesn't like the cereal on it's own, but I mix it with fruits or veggies and he eats it that way, especially with the pears.
That is surprising that the avocado/banana didn't change colour! When I did avocado I just mushed up a small bit at a time, didn't bother making a whole batch because I didn't think it would keep. Maybe I'll try again, blending up a whole one at once, he might like that texture better. Thanks!
