Behavioral Changes

Chris will be four years old this coming 31st of this month. I notice some changes of his behavior one of this is identify clothes if it is for night or day clothes. I tried to teach him about identifying it once but he already got it quick. Sometimes i think that he did not understand what i said but i underestimate my son since he is really an energetic kid ever. It gives me headache but i love him and tried to do something productive for him. I teach him many things and hoping he will learn fast hehehe. What do you do when your son will not listen to you or talk loud? hehehhe. Chris is like his daddy has a very loud voice sometimes i confront him because it is very noisy that people will not like it. It was three times already the front desk of the hotel told us to let Chris behave. We need to go back to the house so that he can play and have many room to do kids thing....
