A world of practical tasks and activities is opening up
Being able to turn their forearm now enables your baby to try to pick up and use objects like a cup handle, spoon, or sponge in the bath.
This skill will eventually lead to their ability to use objects as tools, play sports and so much more. From using cutlery or snipping with scissors, to throwing underarm and turning a key, the ability to rotate our forearm is essential to so many things we do in life.[1]
