Three year olds are at an exciting age where they are starting to become more independent and curious about the world around them. For Christmas, you could consider getting them educational toys that encourage learning and exploration, such as blocks, puzzles, or a pretend play set. You could also consider getting them a toy that helps with their coordination and motor skills, such as a ball or a tricycle. Additionally, you could consider getting them a book or a toy that sparks their imagination and creativity. Whatever you choose, make sure it is age appropriate and will keep them engaged and entertained.
