If your child asks a question, it is because he wants to know the answer. Of course depending on the age of your child, you respond appropriately, but never brush off their question as not being important. The fact that your child asks you a question, shows that he is curious. He has a desire to discover the world he is growing up in and a need to interact with you and you with him. The question is important to your child based upon his current points of reference, or he would not have asked it
He will value your undivided attention so much, which will become evident in later years, when you ask him a question, or need an answer. He will give it to you, because that has always been the way you have treated him. As his father, you lead by example.
It is at a very early age that you should set the ground rules for the quality of communication between you and your children. This will determine what happens throughout their whole childhood. If you get this right, at the start of their lives, it will reap immeasurable benefits for the quality of your relationship together in later years. This will be very evident during their teenage years, when the challenges are very different, and can sometimes seem insurmountable for both of you.
Think of the amount of times you have heard fathers say to their child “ask me later”, or “go and ask your mother”. By doing this, you are sending a subliminal message to your child. ‘I do not have time for you right now’, or ‘I’m not interested in what you want to know’, or even ‘it doesn’t concern me’. Potentially this can be the start of the construction of subconscious barriers to communication with your child, which as he gets older will be very hard to overcome and could lead to serious consequences in later years.
