I bought the Rainbow Light powder stuff that was recommended to me on here...
Yeah, he won't drink it. IF we can force it down him he drinks about half of it. I've put it in everything (including smoothies) and he won't do it. (OH, and when it says "easy dissolve" or whatever...it lied)
He doesn't eat anything pureed (well, the problem is that he doesn't eat much of anything these days)
I even tried to cut off part of the nipple of a bottle and sneak it in a smoothie like that (he won't drink it out of the straw cup that he loves...Mommy's smoothie? Sure, we'll drink that. DS's smoothie? Nope, won't do it) he got two sips in and then tried to pour it out.
These were expensive, dangit. I feel like the sink gets more of it than he does. I'm so frustrated and worried.
