What I did was push the pins in flush with the plastic body of the header using pliers and inserted them from the component side of the daughter board. This is the strip that you see at the bottom of the board.The plastic body acts as a stop & a small amount of solder on the solder side holds it in place without interfering with the mating to the female header. I break the headers into six & four pins as I use the displays in 4 bit mode so 4 data lines are not used so I can't see wasting the pin strip.
