1.-A advice that I can give you is that you should tell a story to your daughter and that they don't watch horror movies because then they don't want to sleep in their own bed because they think that they may appear, they have to tell them that there are no such movie characters .
2.-the child wet the bed because something bad must have happened to him, so he must go to a psychologist to tell him about his problem of what happened to him at school.
3.-What happens is that your baby does not tolerate food because they do not like him according to his intestine. Some babies are intolerant to certain foods, so you would have to go to the pediatrician to prescribe something they can eat. your baby.
4.-Your son gets mad uncontrollably because it is the way of expressing the rebellion that he has inside because you don't listen to him when buying what he wants for food or drink.
5.-It is a form of rebellion of your son to speak obsessively so that his parents pay attention to him, which is why I advise them to take him to a specialist to see what is happening to him because maybe they bully him at his school.
