Question

After several weeks of crawling, ben learned to avoid going headfirst down a steep incline. now he has started to walk. can his parents trust him not to try walking down a steep surface? explain.

Answer 1

No, they shouldn't

An infant that just learn to walk still hasn't developed observational and reflex skills necessary to go headfirst down a steep incline.
When adult falls, our brain will response in such a way to prevent us from falling in dangerous position. Infant stitt hasn't developed this response, so one single fall will be really fatal
