How to know if its enough

Bailey

My baby is 6 days old and I have been ebf. In the hospital she would eat for 10 minutes on each side. Now that my milk has come in she is only wanting to eat 10 minutes on one side then seems done. She is having plenty of wet and dirty diapers and the pediatrician was very happy with her weight. Is she eating for long enough ? I’m a first time mom and concerned 10 minutes isn’t enough. Thanks in advance! ❤️
