Fisher Price Rock and Play

While driving in a car there are different bumps... stop... starts.... different speeds.... different terrains etc.

You don't see positional asphyxia in car seats because the ever changeing positioning.

With seats and swings they have one movement or are completely still. It doesn't awaken the baby... it doesn't stimulate breating.

That makes tons of sense! Thanks Nan!
