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."
