7 week old BF only 11-15 min total?

Jill • FTM to the cutest baby boy, Jude 😍👶🏻💙
My little guy used to average 20-30 minutes total (10-15 on each side), but lately he's been eating 11-15 minutes total and acting full. Is this normal? Anyone else deal with this? He seems too young to be getting so efficient, and I'm worried he's not getting enough
