Which GI change occurs as an infant grows?

Which GI change occurs as an infant grows?

• A. Stomach capacity increases and first primary teeth erupt between 6-8 months
• B. Stomach capacity decreases and teeth erupt at 2-3 years
• C. Stomach capacity remains constant and no teething until 12 months
• D. Stomach capacity increases but teeth erupt at 12-14 months

Answer: (A)

As infants grow, the GI system and dentition develop together: the stomach expands to accommodate larger feeds, and teething begins in the first year. The first primary teeth typically erupt around 6 to 8 months, marking the start of dental development while feeding needs increase. This combination—increasing stomach capacity and eruption of the first primary teeth around 6–8 months—fits the expected pattern of infancy growth. The other options misstate either the stomach's change (it does not decrease or stay constant) or the timing of teething (first teeth usually appear earlier than 12 months).
