This allowed their imaginations to allow more risks because they knew regardless, they'd be fine in the end, as opposed to seeing the world as a scary place and not knowing the consequences.
Though, that's just justification after the fact - Early seasons had Tommy getting kidnapped multiple times, the babies running away, getting stuck in environments that nearly killed them - The later seasons definitely smoothed out that aspect for mainstream appeal.
