Final answer:
Two and three year olds commonly switch hand preference as they are refining their motor skills and hand preferences.
Step-by-step explanation:
Yes, it is common for two and three year olds to switch hand preference for some activities. During early childhood, children are still developing their motor skills and exploring their physical abilities. This exploratory phase includes trying different hands for various tasks, leading to occasional hand switching when performing activities. It's a part of their fine motor skills development. By the age of three, most children begin to establish a preference for using one hand over the other, but it is still normal for them to switch hands as they master different tasks and their preferences solidify.
