Final answer:
Most children are able to feed themselves with a bottle or cup and communicate their basic needs by age 2. This is when they also develop better motor skills and a vocabulary to express themselves.
Step-by-step explanation:
By what age do most children attain the ability to feed themselves with a bottle, a spoon, or a cup, and also communicate their basic needs to caregivers? The answer is B) 2 years. By their first birthday, most toddlers have developed motor skills that enable them to drink from a cup, although with frequent spills. By two years of age, toddlers have rapidly expanded their vocabulary to around 50 words and can understand many more, allowing them to communicate their needs more effectively. They also develop the cognitive ability to follow simple commands and help with dressing, which aids in their independence in feeding and other basic tasks.
