Child development at age 9-12 months


This period should prepare the child for becoming a toddler. It is marked by the child's growing independence, albeit within the sheltered familial environment. This happens by the child learning to walk and to interact verbally with its caregivers. Children should gradually be introduced to a healthy family diet  in order to allow the child to participate in family meals and still meet nutritional requirements after its first birthday.

Baby’s body


Learning crawl up the stairs and to walk with assistance, babies' bodies develop remarkably between the ages of 9-12 months, and of course, the child's independence grows with it.

Baby’s mind


In this period, a baby's word pool starts to build and babies utter their first consonants and tones. In some cases, babies even speak their first words. They also become increasingly independent regarding their mind; forming their own opinion, participating in clothing selection, and getting attached to a favourite toy, for instance.

Nutrition


Infant nutrition should be as healthy and as natural as possible, particularly  regarding low sugar and salt content. Since the child is still exploring new food, it is important to offer a variety of different foods including various vegetables, fruits, meat, and fish (Koletzko et al, 2013). This also ensures that the required energy intake of approximately 700kcal per day and a balanced nutrient supply have been provided. Foods should be rich in vitamins A, C, and D because they are important in infant nutrition at the age of 9-12 months. They deliver a variety of health advantages for the child, such as supporting the immune system and the development of the eyes, improving bone health, and providing antioxidant and other functions.
