Please help. My 4 year old is a nightmare at the moment re not listening to anything DH or I ask him to do. It normally takes about 5 or 6 tellings and ends in me shouting at him to get stuff done. Also, he always has an answer for everything and is continually speaking back. Is this just normal development for his age and what can I do to try to prevent it as I am at my wits end with him now? Please help.
