Getting to grips with in-hand manipulation
In-hand manipulation is the ability to move objects around the hand, and position them, without using your other hand. This is something we use often in everyday life, for example, when we pick up a coin and put it in the slot to pay for parking, put the lid on the toothpaste, or pick up a pen and write.
Your toddler is probably starting to get more confident doing this, perhaps picking up food and holding it in their palm before moving it to their fingertips so they can eat.
