What is the term used for the initial stage in the growth process of young animals or children?

The initial stage in the growth process of young animals or children is referred to as weaning. This is the phase in which a young mammal transitions from breastfeeding or nursing to consuming solid food. During weaning, the young are gradually taught to eat a more diverse diet, which is crucial for their development and independence as they grow. This process is essential because it helps young animals build the necessary skills to find food on their own, ensuring their survival when they eventually become independent.

In the context of development, weaning is a significant milestone that marks the shift in their diet and can influence their health and nutritional status. This transition is important in various species and is often accompanied by behavioral and physical changes that are necessary for the young to thrive in their environment.
