Try changing her diaper during a feeding to wake her. Take her cloths off. You dont want her to comfy. I used to get a cold glass of ice water and put it on my sons foot or tummy to wake him and we would tickle and sing loud. Also she is still so young at 1 week old she will figure it out soon. Just keep sticking to it.
Also dont try and keep her awake during the day so she will sleep at night - let her sleep when she wants she is too young. Newborns can only stay awake 1-2 hours and from when they wake. And mine was only up for an hour if that. At night when she is awake keep lights off / dim and dont talk to her...no TV around her and she will get it.
