Baby won’t eat 😫

My milk just came in today, she’s three days old, and I’m having the hardest time getting her to nurse. She won’t nurse every 2-3 hours like she’s suppose to and I’ll try and try and try to get her to but she refuses to latch on even with a nipple shield. Am I stressing too much about it being every 2-3 hours or should I just let her decide when she wants to be fed?
