Final answer:
Babies at the Crawler stage begin to use a spoon as part of their self-feeding practice, enabled by the development of their pincer grip around ten months of age.
Step-by-step explanation:
The self-feeding practice that a baby at the Crawler stage may start using is the ability to use a spoon. At around ten months old, a baby develops the pincer grip, which involves coordinating the thumb and forefinger to pick up small objects, like pieces of food. This coordination also enables them to attempt to feed themselves with a spoon, becoming more independent during meal times. Self-feeding is a crucial part of a child’s motor skill development and encourages their growth towards independence. It is a messy process, but it plays a significant role in the progression of a baby’s fine motor skills and hand-eye coordination.
