I was delighted to hear of your great news. How proud and thankful you must be! Steve too must be very proud of his son and heir.
I know it is no good hoping to see you just yet, but I shall come over as soon as you are able to receive visitors. Meanwhile, I hope you and the son are going on well, and continue to do so.
My love and congratulations to the proud Father and Mother, and kisses to their young son.
Your affectionate friend,
