Why does the baby's thumb turn inward?

After the baby is born, the flexor muscles are more developed than the extensor muscles, which will cause the baby's thumb to turn inward. Usually, you should give your child more stretching massage. Push from the palm of your hand toward your five fingers, and slowly the baby will be able to stretch out. However, by six to seven months, the baby should be able to extend the index finger. If the baby's thumb is still turned inward, you must go to the hospital for a check-up, as this may be one of the symptoms of cerebral palsy.

The development of the limbs on both sides of a person should be symmetrical. If one side is underdeveloped, there may be problems with spasms in the motor muscles controlled by the motor nerves. A 4-month-old baby often uses his entire palm to hold objects. At 7 months, the baby can use the thumb and other two fingers to hold objects. It's normal for your baby to grasp with his hands. A 5-month-old baby will use both hands to actively pick up things and put everything in his mouth. When you use both hands to hold something, it is abnormal that the hand cannot be stretched out actively.

If the baby's thumb muscles are not able to stretch outwards when stretching his right hand, then the baby's thumb will be adducted. This shows that the motor muscles of the baby's arm on this side are not stretched long enough and the muscle tension is abnormal, which affects the normal function of the baby's thumb. Give the baby's inward-turned thumb and arm a stretching massage. After the massage, fix the thumb with a handkerchief to ensure that the thumb is in the outward position. But be careful not to wrap it too tightly to avoid blood flow restriction, and loosen it if your thumb turns purple. If you do this every day, you will gradually see results.

After 3 months, the baby's fingers will be able to open. It is abnormal if one baby can open the other one. Go to the Children's Hospital for a neurological checkup.

Generally, premature babies less than 7 months old will not have reactions such as clenching fists or curling legs. Even if the weather is very cold, new mothers do not need to worry, but mothers can help babies massage their palms every day, especially the arc part between the thumb and index finger, to help babies get used to straightening their fingers! Generally, the thumb adduction should disappear after three months. If the thumb is still adducted at five months, it is an abnormal posture. In this case, you should take your baby to the hospital for examination and treatment. Early mild cerebral palsy can be cured.
