hi just wondering my lo is 4 mths and he was sick with a cold for over a week. But now he much better and is feeding is good again. I am wondering before he was sick he was taking 5 oz every 3 hours now we hav moved him to 4 hour and tried him with 6 oz but he was still crying for food and finsihing bottles so uped him to 7 oz. Now he takes the whole bottle but only took 3 oz of df just wondering is this to much. Also think he going throw teething and growth spurt at same time.
