How many 'ice-cube-sized' portions does LO eat in one sitting? In case you don't know what I'm talking about, I freeze the purees into ice cube trays and then pop them out and store them in ziploc bags.
In one sitting, we usually go through two cubes worth of food, plus some rice or oatmeal cereal to thicken it and some breastmilk to thin it. Sometimes she will really only want one cube worth of food.
How much food is your LO getting down per meal and how many meals are you doing?
