This is the clearest screencap I could find of the birth announcement, but I thought it was something that definitely needs to be talked about here. The left side definitely says "Mr and Mrs DiLaurentis take pleasure in announcing the birth of a son, Jason Matthew" on the top half, but the bottom is much more difficult to make out except for ending in "Los Angeles, California". The second starts and ends the same way, but has a different name name after "birth of a son", it looks to me like Bradley Todd, but I can't be certain.

What's the most interesting to me is that the second name is not Charles, and the fact that the birth announcements have different text on the bottom half. Now, it's possible this was a prop made before the name Charles was told to the people in charge of props and was never meant for the text to be readable, but it also could be a clue.

ETA: Playing with it in photoshop and trying all the guesses revealed this full translation, which I typed out in a post below:
