Overall, babies become more skilled with regard to coordinating their own body. They become more mobile at age 6-9 months, learning to crawl and to move to a sitting position by themselves.
Between 6-9 months, babies make particular progress in communication. This refers to understanding their own name and one-word requests, but also to expressing themselves using simple gestures and consonants.
At 6 months of age, the recommended period of exclusive breastfeeding ends (WHO, 2009). This means that the child is gradually introduced to other food sources in order to meet the required energy consumption of around 600kcal per day. For a gentle adjustment, it is recommended to start with single ingredient meals (i.e. one specific fruit, vegetable, or grain only) and increase both the amount of food as well as the variety within the meal step by step. At the same time, the texture can be slowly changed from pureed to mashed and chopped foods (WHO, 2009). At this age, vitamin B12, iodine, and selenium are highly beneficial nutrients. While vitamin B12 is mainly involved in important isomerisation processes, iodine is particularly important for the development of the baby’s brain and selenium supports its immune system.
At age 6-9 months, the main motoric milestones are:
