From an individual perspective, there are significant differences in the pace of development among different babies. Some babies may develop better and learn faster, while others may develop slower. However, overall, the development of babies still has a certain standard and a relatively average normal range. The standard for intellectual development of a 1-year-old baby should be evaluated from the following aspects.
1. Language proficiency
A baby's language ability is also a major indicator of intelligence evaluation. Generally speaking, a 1-year-old baby can already say some simple words and short sentences, such as calling their parents and other family members, using fragmented words to express their wishes, and can also understand some instructions from adults, such as asking them to pick up a small toy, and imitating the sounds of animals with adults.
2. Cognitive ability
A 1-year-old baby already has certain cognitive abilities and knows the meaning of refusal and agreement. If they are unwilling to engage in a certain activity, they will express it through language or body language. Can identify one's own clothes, toys, and daily utensils, and also follow certain rules to play games, such as building blocks and putting toys into boxes and taking them out, to find hidden items.
3. Action ability
In addition to instinctive action reactions, the development of intelligence in a 1-year-old baby will prompt them to make conscious actions, such as informing adults in some way when they need to defecate, lifting their arms when dressing them, and lifting their feet when putting on shoes.
