The Montessori egg is from Carter’s @lovevery kit. A Montessori style play kit designed by experts for stage based learning. This simple egg is quite useful; it helps your baby learn to use both sides of their body at the same time, a skill that’s important for future tasks like getting dressed. Your baby needs lots of experience using both hands at once. This practice builds the speed of communication between their brain’s two hemispheres. The egg is hand down his favorite along with the scarf for peek-a-boo. Great for imaginary play, language development, and tossing. The scarf SAVES me during diaper time at this age!
