Development of infants between 3 and 6 months

Gross Motor Development

By the time babies are 3 months old, they have better upper body control. You can raise your head and chest. Sometimes they roll themselves from the supine to the prone position. By 6 months of age, some babies will begin to slide, and some will be able to sit up with support. If they are supported by us, their feet can already carry part of their body weight.

Taking into account the developmental needs of this period, our Montessori educators recommend a Montessori kickball with bells to encourage babies to use their arms and legs and improve their movement.

This Montessori patchball can later be used as a rolling ball when babies start to crawl.

Fun things like bells, buttons or ribbons can also be sewn onto baby's socks. These will attract baby's attention and he will try to put them in his mouth, which will help his coordination skills.

We have also provided a basket of soft balls of different sizes and textures for baby. Because these balls are soft and don't roll as quickly, babies can grab them with one hand, then roll and grab again. They entice babies to move and crawl towards them.

We suggest parents set up a shelf for their baby and place the balls and other learning aids on it. It should be within sight but some distance from the exercise mat so that the baby has to move to get to the learning resources. When we put the toy in the baby's hand, it has little incentive to move. We put the toy or something that attracts the baby a little further away from him to encourage movement. He will keep watching, and one day he will try to move toward it, which he slowly but surely succeeds in doing. Different babies find different techniques to move. Some slide, some roll. Each of these skills requires effort and perseverance from our babies, and you are the beginning of character development for life.

When our babies start to slide, we can roll the ball close to them, but not too fast or too far. These rolling objects encourage our babies to move and give them the satisfaction of achieving their goals, subconsciously learning that they are capable of doing things themselves. They grab, they grab, they grab again, and then they catch! These little victories stick in our babies minds. These small successes are deposits in the trust bank of our babies. They build a basic confidence in themselves and their abilities.

Fine motor skills

Between the 4th and 6th month of life, myelination develops in the shoulders and arms. Children begin to consciously reach for toys in front of them, pick them up and play with them, or put them in their mouths and explore. Her eyesight also becomes clear. If you watch them, you will see that they are very interested in their hands. Babies' grasping ability also develops rapidly during this period, and the ability to grasp and squeeze with fingers becomes more and more precise, and the eye-hand cooperation becomes more coordinated.

So we have developed a range of grasping toys for this time to encourage grasping development. The different shapes, textures and weights of the toys encourage babies to use their hands in different ways. Rattles are made from different materials to give them different tactile experiences. For example, metal feels cooler and softer than wood. This collection also includes toys that make sounds when touched and shaken, stimulating baby's auditory senses and increasing their interest in play. It should be noted that babies put these toys in their mouths, so our toys are made from the safest natural materials.

Remember that every child is different. The age given by us is only a guide for a rough age range.
