Mason has been pulling himself up on the Montessori shelves so to give him some encouragement with his cruising and becoming mobile i put up a peek-a-boo mirror on the end of the shelves for him to find.I simple double sided taped a shatterproof mirror to the shelves and also double sided taped a piece of fabric a little bigger than the mirror over the top.
Watching him explore it and was lovely. His little face lit up when he lifted the flap of fabric. I later had to move it up slightly to encourage him to stand up and balance as at this height it was easier for him to sit while playing.
Object Permanence is a Montessori principle that is often shown in the 9-12 month age group. Working in child care you often find around this age children become "clingy" or not wanting their caregiver to leave their sight. Giving Mason the opportunity to explore these Object permanence boxes reinforces that even though you may not see something it is still there.
As he drops the ball into the hole, he looses sight of it and has to open the draw to find it. This focus' on his hand eye coordination,fine motor skills and starts the process of his memory understanding object permanence.
