What is the maximum age for a child to be considered an infant?

In the context of child development and care, an infant is commonly defined as a child who is 1 year old or younger. Therefore, the correct response indicates that the maximum age for a child to be considered an infant is 1 year. This terminology aligns with health and development guidelines, which specify that infants typically include newborns and babies up to 12 months of age.

Understanding developmental milestones is crucial for caregivers, as infants undergo significant growth and changes within that first year. Infants require specific care, nutrition, and attention that differ from that of older children. Recognizing age classifications helps ensure that care providers can meet developmental needs appropriately.
