My kitten doesn’t seem to eat her dry food

Okay i just got a kitten she is about 6 weeks old. Tomorrow will be the first time she will be home alone without me or my boyfriend. In the morning i usually mix her wet food and dry food and so does my boyfriend a little while after. Im tryna warm her up to just dry food bc i know wet food can’t sit out or it’ll go bad. But my kitty just won’t eat her dry food and i dont want her to not eat til i get home which is 5:30. (My boyfriend leaves work for 11 am and wont get off til 9:30). What should i do?
