Well, you have to admit, the mentality and knowledge in doing the natural thing of giving birth to a child has changed in this country, and for the good.
I remember growing up in the 50’s and 60’s, when my mother gave birth to my two younger brothers. In those days, there was no birthing classes. Mothers went to the hospital, without any clue other than that they would suffer great pain and the doctor would often us forceps, as in my self and all four brothers were delivered. Fathers went home or waited in the waiting room. Mothers stayed in the hospital at least five days before going home, and no one except the father,(who had to wear a gown and mask) was allowed in the room while the baby was with her.
Then, when the mother and baby finally arrived home, no visitors for the first month were allowed, and Baptisms were usually scheduled right after the 30 day wait period. Mothers of course were still recovering from giving birth, and they were ordered to stay home by their doctors so hence, the God mother took the child to the Baptism.
Look how its changed. Both parents take classes on child birth. When the baby arrives, everyone is allowed in the room to see the new baby and everyone gets to hold the baby. This was unheard of back before the 70’s. Also, in todays world(United States specifically) a woman gives birth and the next day she’s home and that week in many cases, is out visiting friends and relatives with her new born child. So, it would be unthinkable, that she would not be at the Baptism holding her child.
As far as the god parents losing the knowledge of what their role is, in helping raise the child in the faith? I think god parents know that role better today than in the old days. Back then, god parents and parents, thought that the role of god parents, was to raise the child if both parents should die for some reason.
I know in my own case and that of my grandchildren, we know a lot more about what Baptism is, than what parents did years back.
