'Motionese' and how it helps your baby
This simplification of actions is called 'infant-directed action' or 'motionese'. When you interact with your baby, you'll be closer to them than you would be to an adult; without even thinking about it, you'll repeat actions more, and look at your baby’s face more often.
It is thought that ‘motionese’ helps babies to have a greater level of attention and might help them to focus on a particular goal.
Scientists think that parents instinctively change their actions in this way when playing with their babies, so you probably don’t need to do anything differently, just try to have some uninterrupted time playing with your baby as often as you can.
