I was skeptical to try this with the reviews about the taste as my son is super picky and an always spot when I add things to his liquid or food. It mixed perfectly with a 1/4 cup warm water and then I added his flavor packet and cold water to his sippy cup. He drank it right down. Now it smells awful but I even didn't noticed a taste. We just started 2 days ago because he has slowed down on his normal eating and I also would hope it will help him with the agitation he has started at bedtime.
