It is impossible to spoil a child who is younger than 1 year old.

Infants younger than 1 year old are not developmentally capable of understanding or manipulating their environment in a way that would constitute being "spoiled". They are completely dependent on their caregivers for all their needs and do not have the cognitive ability to intentionally manipulate their caregivers for their own benefit. However, it is important for parents and caregivers to provide consistent and responsive care for infants to support their healthy development.
