The very first Baby Alive!
The first Baby Alive dolls were introduced by Kenner in the 70's.
To my knowledge Kenner was the first toy company to come up with a baby doll that actually pooped it's diapers!
The dolls could be fed food packets mixed with water, and came with a bottle, diapers, and feeding spoon. When you pressed the baby's chin, her mouth would move in a slow sucking motion and the food would slide through her body and into her diaper.
The very first version did not speak, so you had to check the diaper a few moments after feeding.
