An "SGA infant" refers to a baby who is smaller than expected for their gestational age, meaning they're born weighing less than 90% of other babies at the same stage of pregnancy. It's like being the shortest kid in your class β you're still you, but a bit tinier than average. This can happen for many reasons, from genetics to nutrition during pregnancy. While some catch up quickly, others might need a little extra care to thrive. Think of a premature seedling requiring more attention to grow strong.
