what age should you tell a child about his biological father
The fact that his biological father wants court action to claim his child make the issue less complicated. It is important that the child knows his or her biological father and since you are being forced into making that decision at this early age, I suggest you do it and enjoy the relief. Now the important thing is that the child be surrounded by love and that you understand what makes a father a father.
The child will attach itself to the father that shows the most loving-kindness. So you have done your part and the urgency now lies on your husband to be loving father.
At the young age of 3 yrs. old the child will not understand the difference between biological or otherwise but it will understanding and believe to be his father the one with whom you sleep at nights, who teaches the child how to ride the bicycle and the one with whom he spends quality time. Sister, when the devil gives you a lemon, don't be disheartened, but make lemonade.
