Final answer:
During infancy, a well-nourished infant typically gains weight and length at a rapid pace. This growth is an important indicator of their overall health and development. Regular check-ups with a pediatrician are necessary to monitor a baby's growth and ensure they are meeting their milestones.
Step-by-step explanation:
In infancy, a well-nourished infant typically gains weight and length. They may gain about 28 g (1 oz) per day during the first two months and slow down to about 0.45 kg (1 lb) per month for the remainder of the first year. By the end of the first year, an infant generally doubles its birth weight and may close to double its birth length.
This growth in weight and length is an important indicator of a baby's overall health and development. It shows that the baby is getting adequate nutrition and is growing at a normal rate. The number of wet diapers and frequent stools also indicate that the baby is properly hydrated and their digestive system is functioning well.
However, it is important to note that every baby is unique, and there may be variations in individual growth patterns. Regular check-ups with a pediatrician are essential to monitor a baby's growth and ensure they are meeting their developmental milestones.
