Do you?

Feed your baby on a schedule? I have been feeding my baby on what I think is a schedule but I feel like I fail some days because I follow the stupid schedule in my head where I think she only eats at a certain time. She is almost 2 months old weighing 7lbs 14oz and I formula feed her. She will eat 5oz every 3 3/12 hours. Sometimes after a feeding she will cry an hour an half or so later and I figure out she is still hungry. So I make an 1 or 2oz bottle and feed her more then she is fine. Am I doing this right? I dont know what the right way or wrong way to do this but any advice? 😳
