As babies are just born, their cerebral cortex is not yet mature enough, and their nerves are limited in their ability to regulate the muscles of the hand. To put it plainly, compared to the action of the fingers to stretch out, the baby is more likely to bend the fingers, thus causing the fingers to tighten their grip, can not freely open and tighten. This is actually a normal physiological phenomenon, medically known as the “fist reflex”, 3 months ago, the daytime fist time more than open time; 3 months later, about half the time to open, half the time to make a fist; 4 months later, the baby’s hands basically open, which for the baby began to actively grasp the toys to lay the foundation. However, due to individual differences, there are also many babies whose hands will always be in an extended state. At this time, as long as the baby’s growth and development indicators are normal, parents do not need to worry too much. However, if the baby’s finger joints can not move or touch the baby’s little palm with your finger, will not curl up the little finger to hold your finger (grasping reflex), then you need to go to the hospital to see a doctor. Training baby’s grasping ability in stages 1, 1 to 3 months Baby especially like to look at their own hands, play with their own hands, sucking their own hands, this is the inevitable stage of the baby’s psychological development, so the mother can not interfere, but also should provide conditions to assist the baby to play with their hands, for example, the hand tied to a red cloth, wearing a clattering bracelets and so on. But pay attention to the baby’s hands clean and hygienic. 2, 4 ~ 8 months 4 months old, your baby can grasp large objects, such as blocks. He can’t grasp small objects like peas yet, and that will have to wait until his fingers develop more dexterity to do so. When your baby is close to getting his first tooth (usually between 3 and 12 months), he will start grabbing things around to put in his mouth. If your baby is eating a complementary food, he won’t be able to hold the spoon very securely yet, but he will try hard. Your baby can paddle things in his direction and will also start to switch things from one hand to the other. From this point on, it’s a good idea to put away all valuables out of your baby’s reach and make sure you have a safe home environment: to prevent your baby from choking on small objects. 3. 9 to 12 months Your baby can now pick things up easily. By this time, your baby is showing a preference for either left- or right-handedness, but you won’t know for sure if he’s left-handed until he’s 2 or 3 years old. Your baby is still perfecting the pinching action of picking up objects, which involves pinching small objects with the thumb and forefinger. As your baby’s coordination improves, he will soon become quite adept at using spoons and other utensils to eat, although he may prefer to hold the spoon in one hand and actually use the fingers of the other hand to grab things to eat. Daily life mom can do this 1, don’t forget to wash the baby’s hands when bathing, the fingertips gently into the baby’s palm, gently turning back and forth in the heart of the little hand, while cleaning and massage; 2, breastfeeding the baby in his arms, put his fingers into his hand, big hand holding a small hand, gently touching a touch, slowly shaking a shake, open baby’s fists, so that the little hand to touch the mother’s face, and keep and Baby talk, feel the warmth of mom’s skin, baby satisfaction and comfortable. 3, the baby ate and drank enough, happy mood, you can give the baby’s small hands to do massage, the gentle touch of the skin can stimulate the baby’s tactile nerves, so that the baby’s physical and mental relaxation, the small fists are easy to loosen up. 4, encourage the baby to frequent “punch”, practice hand-eye coordination, touch, grasp things. 5, parents also need to regularly help the baby to trim the nails, so that the baby will not learn to stretch their hands after accidentally scratch themselves. Hand and baby’s brain development is closely related to the hand movements can promote the development of the nervous system, but also to induce the infant psychological development plays a role in the premise. After the fingers are separated, you can fiddle with all kinds of objects as you like, so that babies can actively learn and engage in various activities, perception and concrete thinking ability to develop. Parents should usually pay attention to observe whether the baby has abnormal symptoms. Within half a year old is the fastest period of brain cell development and maturation of brain function, so you should take your baby to the hospital regularly for checkups, and you can get timely treatment if there are symptoms of cerebral palsy with developmental delay.
