As the Teaching Littles website points out, “One important milestone for toddlers is learning their body parts. It’s adorable when your child starts to point to their eyes and nose; it’s an important skill and part of their language development.”
I’m pleased to find my title Toes, Ears, & Nose! on the list of books they recommend to help teach the subject; the article also includes many other suggestions that will keep the learning fun for your little ones.
