Has anyone had any problems with sma 6months onwards?

idk what sma is lol , but i would start rice into the formula if he isn't satisfied . just to make it thicker . my daughter is 4 & a half months old , and i could never* get her satisfied , but once i added the rice - she was happy (: i started by adding a tsp for every 4 oz to watch for allergies . once i knew she was ok , i upped it to about 2 tsp every 4 . i make her formula daily . ie: i have a 32 oz container & make all the milk for the day . she eats roughly 27 oz a day , i make 28 & add 24 tsp or so . she is doing fine . i suggest a little bit of rice . he is old enough (:
