It is not me, not him, not you, but them (the couple) has a baby and being happy about it. Praise to the Most High of that. Being happy can be celebrated in many ways but one thing for sure is shouting it to family and friends through giving up birth announcements and I cannot agree more. Doing it simply voicing out and letting them know how the couple feel. Being a parent could be the happiest moment of the couple to those who expect it, so why not announce it, isn't it? Congratulations then!
