Quickly place the child's burned or scalded area in cool water and cool it for at least 10 minutes; this will reduce the swelling of the injury. Then remove or cut away the clothing near the wound. If the clothing and the wound are stuck together, do not move it and wait for a doctor to treat it. If the wound is larger than the child's hand, cover the wound with clean plastic wrap or lint-free cloth and take it to the hospital immediately.
2. Choking
If your child suddenly coughs violently, it may be because he or she is choking on something. Parents should immediately check to see if there is anything in the child's mouth. If your hand can reach the choking object, pull it out quickly; if not, let the child lie on his or her lap and pat his or her back with the palm of your hand. If there is no relief, call an ambulance. Keep repeating the first aid action until the ambulance personnel arrives.
3. Strain or sprain
First, wrap a few ice packs in a small towel for 10 minutes, then put on a bandage and elevate the injury to slow the blood flow, which will reduce the degree of bruising and bruising.

4. Electrocution
If the child has not been removed from the power supply after an electric shock, never touch him, the first thing is to cut off the power. If a switch cannot be found, stand on a dry, insulated object (such as a thick telephone book or a stack of newspapers) and pull the power away. The area of injury left on the surface of the body by electrocution may not be large, but there may be damage to the child's internal organs, so be sure to call an ambulance.
5. Poisoning
If a child accidentally ingests a toxic substance, be sure to call an ambulance. Keep the child still until the ambulance arrives. If possible, find out what he has eaten and bring a little to the hospital for laboratory tests. Do not force the child to vomit or risk further damage to the esophagus and stomach. If the child vomits instinctively, collect the vomit and bring it to the hospital. If your child feels a burning sensation in the esophagus or mouth, drink some milk first and wait for medical assistance.
6. Nosebleed
Sit your child down and tilt his head forward so that the nosebleed comes out smoothly. Then have him pinch his nose with his hand and breathe through his mouth. 10 minutes later, if the bleeding does not stop, apply pressure twice more for 10 minutes each time. After stopping the bleeding, wipe the nose clean and tell the child not to talk, cough, or blow his nose to avoid breaking up the freshly clotted blood. However, if the nosebleed does not stop after 30 minutes, it is necessary to send your child to the hospital.
