Why are the baby’s left and right arms different in thickness?

For parents, they definitely need to observe their babies more in daily life, because any parent is worried that their children will suffer from some diseases. Sometimes some parents even find that their baby's arms are of different thicknesses, as if they have a deformity. In this case, parents must be very anxious. Why are the baby's left and right arms different in thickness?

The baby is in the infant stage. If there is no problem with the baby's bone development and the functions are normal, no treatment is needed. It may be a nutrition problem. The nutrition supplied to both sides is different. It doesn’t matter. As you get older, it slowly becomes the same.

Why do babies' arms dislocate easily?

Dislocations often occur in children under 4 years old, but are rare after 6 years old. This is because the upper end of the radial head of children under 4 years old has not yet fully developed, and the elbow joint capsule and ligaments are relatively loose and weak.

What are the symptoms of a dislocated arm?

Many parents are unaware when their baby has a dislocated arm, and the symptoms of an arm dislocation are similar to those of other shoulder or elbow injuries, so it is easy to misdiagnose. Parents should be aware of the symptoms of dislocation so that they can detect the condition as soon as possible and receive timely treatment. After a dislocation, the baby's elbow joint is often in a semi-flexed position, the forearm is in a pronated position, and the baby dare not supinate, cannot lift or pick up objects, and cannot move freely. There is tenderness at the radial head of the elbow joint, but there is no obvious swelling or deformity in the local area. The child refuses to have the affected limb touched by others, but the shoulder, wrist and fingers can move normally. The child usually cries incessantly due to the pain. When dislocation is suspected, parents should use a triangular bandage to fix the baby's affected limb so that the arm is in a relatively comfortable and less painful position, and then go to the hospital immediately. Avoid pulling it hard by yourself.
