I understand staircases are very dangerous for babies.
We have only one staircase at our home. The staircase is 20 cm high.
Our baby is very curious and wants to go down that one staircase (20 cm high) and into the other room to explore it.
I'd like to safely introduce the staircase to my baby. How should I do this? How should I approach teaching a 10 months old baby about the staircase?
