Am I doing breastfeeding wrong?

Laken

My baby is 5 days old and doing great with breastfeeding. My milk just came in yesterday. Is it wrong to offer her to eat every time she cries? Even if she just ate? I mean I thought as long as she latched on she was hungry. I’m just confused because my pediatrician mentioned babies can overeat today and now I wish I would have clarified what he meant....
