Now that we have increased the boys' solids to twice a day, the eating is getting much better. In fact, for the most part I think they prefer solids to milk. We try something new every three days and so far the only absolute rejects are peas and apples (although we sneak apples in everything since we have such an abundance). Successes have been: yams, butternut squash, peaches, banana and avocado. Next on the list are acorn squash, sweet potatoes, pears, and tofu.
As you can see by their man-boobs, they clearly aren't lacking for nutrients!
