The nurse is providing anticipatory guidance to a mother to help promote healthy sleep for her 3-week-old baby. Which recommended guideline might be included in the teaching plan?

A. Advising about increased caloric needs might not be the primary focus unless specific growth concerns are present.
B. At 7 months, while introducing table foods might be on the horizon, it's not the most immediate concern during this well-child visit.
C. Discussing the type of sippy cup to use is pertinent as the infant is approaching an age where the introduction of a sippy cup becomes relevant for transitioning from a bottle.
D. Describing the tongue extrusion reflex might be more relevant for younger infants just starting on solids, typically around 4 to 6 months, rather than at 7 months.

A. Placing the baby on a soft mattress with a firm, flat pillow can increase the risk of Sudden Infant Death Syndrome (SIDS). Infants should sleep on a firm mattress without pillows or soft bedding to reduce the risk of suffocation.
B. Placing the head of the bed near the window for fresh air is not recommended due to potential drafts, temperature changes, or exposure to outdoor elements that might disturb the baby's sleep.
C. Waking a sleeping baby for feedings is generally not advised. Babies will wake on their own when hungry, and consistent nighttime feedings are essential, especially for a 3-week-old infant.
However, advice on this may vary based on the infant's individual health and weight gain, and it's best to follow the pediatrician's guidance.
D. Placing the baby on his or her back when sleeping is the recommended sleep position to reduce the risk of Sudden Infant Death Syndrome (SIDS). This practice is endorsed by pediatric healthcare professionals and is considered a critical guideline for safe infant sleep.
