The process of transitioning an infant’s primary source of nutrition from manufactured formula to animal milk, typically cow’s milk, marks a significant developmental milestone. This dietary shift usually occurs around the first birthday, aligning with evolving nutritional needs and digestive capabilities. It requires careful consideration of the infant’s individual tolerance and potential sensitivities.
This dietary change supports continued growth and development by providing essential nutrients found in milk, such as calcium and vitamin D, crucial for bone health. Furthermore, it represents a step towards a more diverse dietary intake, paving the way for the introduction of a wider range of food groups and textures. Historically, this transition has been guided by pediatric recommendations that prioritize gradual adaptation and monitoring for any adverse reactions.
