An infant has been admitted with failure to thrive (FTT). The nurse knows that more education is needed when one of the parents makes what statement?
1. "I can double the amount of water in the formula to save money."
2. "I need to hold her head up a little higher than her stomach when I feed her."
3. "I need to burp the baby when the feeding is done to get rid of swallowed air."
4. "I need to make sure that the formula is in the nipple so she doesn't swallow so much air."
