Hi, It is common for children to have behavioral changes when they are going through a period of stress or adjustment, such as moving to a new place or starting at a new daycare or kindergarten. At this time, it is essential to be patient and understanding with your child. As for the bed wetting, this is also a common occurrence in young children, particularly when they are going through stressful or emotional situations. Try not to make a big deal out of it, as this can add to your child s anxiety and may make the problem worse. Instead, reassure your child that accidents happen and that you are there to help them. Regarding your son s aggressive behavior, it is important to address this as well. Aggression in young children can have many causes, including frustration, anxiety, and feeling overwhelmed. You can try to redirect his behavior by distracting him with a toy or activity that he enjoys when he is starting to become aggressive. Additionally, make sure that you are setting clear limits and boundaries for him, and that he understands what behaviors are acceptable and what are not. It may be helpful to talk to your son s pediatrician about his behavior and bed wetting. They can provide guidance and support and may refer you to a child psychologist or counselor who can work with your son and help him adjust to his new surroundings. If you require a personalized response, kindly use the Ask A Doctor service and post a follow-up. Take care. Hope I have answered your question. Regards, Dr. Priyanka, General & Family Physician
