a smiling baby is sitting in a white baby bouncer surrounded by toys.
A happy baby bounces with a mobile attached to the bouncer.
A smiling baby does not imply the baby is happy. A baby sitting in a bouncer does not mean the baby bounces. Toys can be items other than a mobile attached to the bouncer.
