Maybe asking a stupid question here, but when did everyone feel comfortable letting their toddler go up and down stairs without supervision? As in, just letting them go up to their room to play and to come down whenever they like without help? I've got a 2 year old (+3 months) and still don't feel comfortable yet but don't know if I'm being unreasonable! Whenever we've gone round other people's houses I haven't felt comfortable with her going upstairs with just the other toddlers on her own as I know she can get silly and excitable and has fallen down a full flight of stairs before. When do I start trusting her? Does she need to be able to walk up and down stairs like an adult before she can do it independently? Am I being overbearing?
