My DS is 4 and still has a stairgate on his bedroom (no reason, just never removed it). He’s nearly dry in the night now though and obviously needs to go to the toilet in the night if needed. Unfortunately his bedroom is right next to the top of the stairs and if he comes out of his room a bit dozy from sleep he could easily fall down them. Is putting stairgate at the top the best solution here or am I missing something better?
