Decreases Breastfeedinf

Jessie

Hi guys, my LO will be 5 weeks tomorrow. The last two days I’ve noticed a decrease in the amount of time he wants to be on my breast when feeding. He would usually feed for about 25 min but now I’m lucky if he stays on for 15.. I’m pretty sure I have a fast let down and he’s having plenty of wet diapers and poops. Should I be concerned his eating as decreased?
