The nurse makes a home visit to a 3-day-old full-term neonate who weighed 3,912 g (8 lb, 10 oz) at birth. Today the neonate, who is being bottlefed, weighs 3,572 g (7 lb, 14 oz). Which of the following instructions should the nurse give to the mother?

1. Continue feeding every 3 to 4 hours since the weight loss is normal.

2. Contact the primary health care provider if the weight loss continues over the next few days.

3. Switch to a soy-based formula because the current one seems inadequate.

4. Change to a higher-calorie formula to prevent further weight loss. Commercial formulas contain 20 calories per 30 mL.
