Just for context, my child is 3 years and 2 months old. We still have baby gates on our town house, so 4 gates in total.
At the moment, we NEVER let him use the stairs alone. If walking upstairs, I always walk behind him or hold his hand and walk alongside him. If he's walking downstairs I will go in front and walk backwards so I can watch him, or hold his hand and walk beside him. When out and about I will always hold his hand.
I'm just wondering at what age I should be able to trust him to do it alone and let him have free range of the house?
He does have a slight visual impairment affecting depth perception.
