I mix it in with whatever breakfast is...with is cereal or fruit or whatever. I've also even mixed it with yogurt/fruit or cottage cheese. My thought it just to get it into them...for the protein, doesn't matter the delivery.
But yes, keep in mind that just because a lo doesn't like it tomorrow, it might be their favorite food next week.
For like 3 weeks my lo "gagged" over peas, now he can eat them straight up and doesn't flinch. I just kept offering them every other day or so, and one time he smiled instead of gagging. Whatever!
