(Subject)- Congratulations letter birth.
Dear friend Tom,
Today I am glad to inform you about the birth of a baby girl in your house. Two days before I came to know about this news. I am really happy for you. I came to know that the mother and the child are both well. But you still need to take care of them. This can be said as a new beginning of your life. Being a father is a lifetime cherished dream but at the same time there are lot of responsibilities . You should give time to your family now. You should cut down some pressure of your work to look after your family.
Now you and your wife are now alone, a new responsibility is with you now. You need to plan about the future of your new born. There are various difficulties in the up bringing of a baby. Thus you should understand things and try to bring a better future for your baby. I wish to god that he blesses your child.
