Up until now, hands were always just an “appendage” from the arms. As your child grows and amplifies their body consciousness, the hands will become the center of much curiosity and awareness.
With four months of life, babies start to discover their hand function as they reach for whatever triggers their curiosity – and afterwards look at it, shake it and, of course, place it in their mouths, if possible. They also like to observe their fingers moving and sucking on them.
How about playing with your child and making them grab your finger, your hair or put their hands on your face? It’s just another idea to stimulate them and make them touch objects with different sizes, materials and textures.
