Play allows children to try out and practice new skills. Children need chances to build upper body strength by pulling themselves up and hanging, by swinging, by rolling balls and by throwing bean bags. They need to strengthen their lower bodies by jumping and balancing.

Parents can help children try different activities, but should not pressure them. Give them time to practice bigger challenges. Ensure their safety but do not overprotect them. Parks are great places where children can use their large motor skills. Play equipment should be big and sturdy, so that children can practice balancing, crawling through, hanging, and climbing.

One in four children 3-5 years old and 8-12 years old have growing pains. The most likely causes of growing pains are jumping, climbing, and other activities that take place during a child's busy day. The pain is usually felt in muscles rather than joints and it varies from mild to strong. Most children who have growing pains do not feel them every day. Massaging, stretching, and applying a warm compress can all help. Help your child by telling them that growing pains will pass as they grow up. Check with your doctor, if your child complains of a lot of pain.
