Patient's question:
Tilt the head back, straighten the waist, arch into a C-shape, and tuck the thumb inwards. Sometimes it can open itself, showing the intention to reach for something, but without using the thumb. The eyes can follow the movement of the object.Doctor's answer:
The child lags behind when pulling up to sit, with the trunk bent into a C-shape, indicating muscle tension in the trunk, which is commonly referred to as the "arching" posture. The thumb is retracted; at 4 months, the child should have fully open fingers. At 4 months, the child can lift their head 90°, actively support themselves with both hands, and lift their chest off the bed, but your child cannot do so. At 4 months, the child can actively grasp objects, but your child cannot. I don't know how the child's sitting posture and standing support posture are. Based on the above information, the child's development is slightly delayed and abnormal. It is recommended that you seek medical attention again and communicate carefully with the doctor.
