During the first three months of pregnancy, there was a small amount of bleeding to preserve the pregnancy, followed by an emergency cesarean section due to failing fetal heart monitoring, resulting in a birth score of 10 out of 10. However, since birth, the child has been sleeping for long periods during the afternoon, more than other children. When hungry, the child cries to be woken up and falls asleep again after eating. When awake, the child dislikes crying and needs to be held. Whenever carried out, the child falls asleep. Even when the soles of the feet are pressed, the child does not wake up. Usually, the child drinks about 600ml of milk daily, which often causes vomiting after drinking, and it is done in large mouthfuls. Now at two and a half months old, the child occasionally smiles unintentionally during naps, but does not laugh when entertained while awake. The child just watches you. The head can be slightly lifted. Personally, it seems that there has been little change since birth, indicating possible mental retardation. The BNP digital biological neural repair technology can stabilize developmental delays in children, adjusting dopamine (DA), serotonin (5-HT), and glutamic acid (GLu) through biological gene regulation. It is safe and effective with no side effects. It is strongly recommended to seek treatment at a professional hospital with a professional doctor who will conduct a thorough examination and treatment. In addition to treating mental retardation, it is suggested that patients pay attention to their diet in daily life and maintain a cheerful mood to enhance their physical condition and accelerate recovery.
