I was born in 1949. When I was young we played outside and watched the clouds and the sky a lot, and I don't remember ever seeing the moon during the day. Is the sun closer to us now so we see it more often or has earth shifted enough to change how we see the moon?
Believe it or not, the Moon was visible during the day in 1949. In fact, the Moon has always been visible during the day at certain parts of the lunar cycle. We know this is true not only because of models of the Earth-Moon system, but there is historical evidence of it!
There are records dating back to ancient China in 2800 BCE of solar eclipses, which are perhaps the most irrefutable evidence of the Moon being present during the day. See this link for the specifics: http://www.timeanddate.com/eclipse/solar-eclipse-history.html
As to why you never observed it during the day, I can only guess. Perhaps you were extremely unlucky and it was always covered by clouds in your area.
But to answer your question, there is no relevant/significant difference in the Sun-Earth-Moon system between 1949 and now.
During daylight, you can only see the moon when the sun is fairly low in the sky and in the correct phase.
For example, about 1 week after full moon you should be able to see it in the morning when the sun is not very high in the eastern sky. At that time, the 1/2 moon should be quite visible between vertically and into the western sky.
Similarly, about 1 week before full moon, you should be able to see the 1/2 moon in the eastern sky when the sun is low in the west.
In the middle of the day, it will be very hard to see the moon.
50 years is nothing on an astronomical scale, so my guess is: you just didn't notice it/pay attention to it/don't remember correctly.
