In general whenever he falls, we usually don’t pick him up immediately when he falls. This looks a bit harsh initially. It is also a bit more harder on us parents because first impulse is to rush and comfort him when he’s hurt himself.
But he’s learnt to a certain extent to rely on himself to comfort himself.
Of course we don’t just leave him there pick him up only few seconds/minutes later, sometimes we pretend as if nothing has happened at all :
