Eating..

My daughter normally eats every 2-3 hrs... She hasn't been eating much today I decided to see how long she goes. She ate at 4am and woke up at 6 refused the boob but was so happy... I offered it to her 2+ times and she finally took it at 11am. 7 hours 😮 than the didn't eat untill 3ish and I also offered it to her 2 times in between... Is this normal? How often does your little one eat? She ate twice last night and a lot. But my boobs are mass full today.
