Help with feeding (first time mom)

rubia

My daughter is 2 months and 6 days old. She has been eating for about 2 weeks 5 ounces every 5 hours. Yesterday she ate at 7 PM and didnt eat again until today 6 am. Then she ate again at 11 am and now its 5 PM and she hasn't gotten up to eat. I read that it's okay to leave her alone until shes hungry but on scared she will start to lose weight. Any advice? This is my first baby
