In order to let your baby can see the clock, you should bend your knee then look around (eye level as same as the baby), now you can imagine how heigh your baby can see.
I bought a wall clock and I put it in the middle of the wall instead of the top of the wall. It is becasue I want my daughter can see it too. Whenever, we walked pass the wall I will introduce my daughter “what time is it now”.
To bring Montessori home, you should think about “Child-Centre”!
